Interpersonal attraction is the foundation of first impressions between potential intimate partners. Relationship scientists suggest that the romantic spark, or "chemistry", that occurs between people is a combination of physical attraction, personal qualities, and a build-up of positive interactions between people.{{Cite journal |last1=Eastwick |first1=Paul W. |last2=Finkel |first2=Eli J. |last3=Joel |first3=Samantha |date=2023 |title=Mate evaluation theory. |journal=Psychological Review |language=en |volume=130 |issue=1 |pages=211–241 |doi=10.1037/rev0000360 |pmid=35389716 |s2cid=248024402 |issn=1939-1471 |doi-access=free }} Researchers find physical attractiveness to be the largest predictor of initial attraction.{{Cite journal |last1=Eastwick |first1=Paul W. |last2=Luchies |first2=Laura B. |last3=Finkel |first3=Eli J. |last4=Hunt |first4=Lucy L. |date=2014 |title=The predictive validity of ideal partner preferences: A review and meta-analysis. |url=http://doi.apa.org/getdoi.cfm?doi=10.1037/a0032432 |journal=Psychological Bulletin |language=en |volume=140 |issue=3 |pages=623–665 |doi=10.1037/a0032432 |pmid=23586697 |issn=1939-1455}} From an evolutionary perspective, this may be because people search for a partner (or potential mate) who displays indicators of good physical health.Graziano, William G.; Bruce, Jennifer Weisho, {{Citation |title=Attraction and the Initiation of Relationships: A Review of the Empirical Literature |date=2018-09-05 |url=http://dx.doi.org/10.4324/9780429020513-24 |work=Handbook of Relationship Initiation |pages=275–301 |access-date=2023-11-01 |publisher=Psychology Press |doi=10.4324/9780429020513-24 |isbn=978-0-429-02051-3|s2cid=210531741 }} Yet, there is also evidence that couples in committed intimate relationships tend to match each other in physical attractiveness, and are rated as similarly physically attractive by both the members of the couple and by outside observers.{{Cite journal |last=Feingold |first=Alan |date=1988 |title=Matching for attractiveness in romantic partners and same-sex friends: A meta-analysis and theoretical critique. |url=http://doi.apa.org/getdoi.cfm?doi=10.1037/0033-2909.104.2.226 |journal=Psychological Bulletin |language=en |volume=104 |issue=2 |pages=226–235 |doi=10.1037/0033-2909.104.2.226 |issn=1939-1455}}{{Cite book |last1=Bradbury |first1=Thomas N. |url= |title=Intimate Relationships |last2=Karney |first2=Benjamin R. |date=2019-07-01 |publisher=W.

When potential intimate partners are getting to know each other, they employ a variety of strategies to increase closeness and gain information about whether the other person is a desirable partner.

Context, timing, and external circumstances influence attraction and whether an individual is receptive to beginning an intimate relationship.

The investment model of commitment is a theoretical framework that suggests that an evaluation of relationship satisfaction, relationship investment, and the quality of alternatives to the relationship impact whether an individual remains in a relationship.

Because relationships are rewarding and evolutionarily necessary, and rejection is a stressful process, people are generally biased toward making decisions that uphold and further facilitate intimate relationships.{{Cite journal |last1=Joel |first1=Samantha |last2=MacDonald |first2=Geoff |date=2021 |title=We're Not That Choosy: Emerging Evidence of a Progression Bias in Romantic Relationships |journal=Personality and Social Psychology Review |language=en |volume=25 |issue=4 |pages=317–343 |doi=10.1177/10888683211025860 |issn=1088-8683 |pmc=8597186 |pmid=34247524}} These biases can lead to distortions in the evaluation of a relationship.

Specific individual characteristics and traits put people at greater risk for experiencing relationship dissolution.

Being married at a younger age, having lower income, lower educational attainment, and cohabiting before marriage are also associated with risk of divorce and relationship dissolution. These characteristics are not necessarily the inherent causes of dissolution.

Common strategies for ending a relationship include justifying the decision, apologizing, avoiding contact (ghosting), or suggesting a "break" period before revisiting the decision.

Advances in legal relationship recognition for same-sex couples have helped normalize and legitimize same-sex intimacy.{{Cite journal |last1=Hopkins |first1=Jason J. |last2=Sorensen |first2=Anna |last3=Taylor |first3=Verta |date=2013 |title=Same-Sex Couples, Families, and Marriage: Embracing and Resisting Heteronormativity 1 |url=https://compass.onlinelibrary.wiley.com/doi/10.1111/soc4.12016 |journal=Sociology Compass |language=en |volume=7 |issue=2 |pages=97–110 |doi=10.1111/soc4.12016 |issn=1751-9020}} Broadly, same-sex and different-sex intimate relationships do not differ significantly, and couples report similar levels of relationship satisfaction and stability.{{Cite journal |last1=Peplau |first1=Letitia Anne |last2=Fingerhut |first2=Adam W. |date=2007 |title=The Close Relationships of Lesbians and Gay Men |url=https://www.annualreviews.org/doi/10.1146/annurev.psych.58.110405.085701 |journal=Annual Review of Psychology |language=en |volume=58 |issue=1 |pages=405–424 |doi=10.1146/annurev.psych.58.110405.085701 |pmid=16903800 |issn=0066-4308}} However, research supports a few common differences between same-sex and different-sex intimacy. In the relationship formation period, the boundaries between friendship and romantic intimacy may be more nuanced and complex among sexual minorities.{{Cite journal |last1=Diamond |first1=Lisa M. |last2=Dubé |first2=Eric M. |date=2002 |title=Friendship and Attachment Among Heterosexual and Sexual-Minority Youths: Does the Gender of Your Friend Matter? |url=http://link.springer.com/10.1023/A:1014026111486 |journal=Journal of Youth and Adolescence |language=en |volume=31 |issue=2 |pages=155–166 |doi=10.1023/A:1014026111486 |s2cid=142987585 |issn=0047-2891}} For instance, many lesbian women report that their romantic relationships developed from an existing friendship.{{Cite journal |last=Vetere |first=Victoria A. |date=1982 |title=The Role of Friendship in the Development and Maintenance of Lesbian Love Relationships |url=http://www.tandfonline.com/doi/abs/10.1300/J082v08n02_07 |journal=Journal of Homosexuality |language=en |volume=8 |issue=2 |pages=51–65 |doi=10.1300/J082v08n02_07 |pmid=7166643 |issn=0091-8369}} Certain relationship maintenance practices also differ. While heterosexual relationships might rely on traditional gender roles to divide labor and decision-making power, same-sex couples are more likely to divide housework evenly. Lesbian couples report lower frequency of sex compared to heterosexual couples, and gay men are more likely to engage in non-monogamy.{{Cite journal |last1=Parsons |first1=Jeffrey T. |last2=Starks |first2=Tyrel J. |last3=Gamarel |first3=Kristi E. |last4=Grov |first4=Christian |date=2012 |title=Non-monogamy and sexual relationship quality among same-sex male couples |url=https://pubmed.ncbi.nlm.nih.gov/22906124/ |journal=Journal of Family Psychology |volume=26 |issue=5 |pages=669–677 |doi=10.1037/a0029561 |issn=1939-1293 |pmid=22906124}}

Same-sex relationships face unique challenges with regards to stigma, discrimination, and social support.

Some asexual people engage in intimate relationships that are solely emotionally intimate, but other asexual people's relationships involve sex as part of negotiations with non-asexual partners.{{Cite web |title=Understanding the Asexual Community |url=https://www.hrc.org/resources/understanding-the-asexual-community |access-date=2023-11-17 |website=Human Rights Campaign |language=en-US}}{{Cite journal |last=Chasin |first=CJ DeLuzio |date=2015 |title=Making Sense in and of the Asexual Community: Navigating Relationships and Identities in a Context of Resistance |url=https://onlinelibrary.wiley.com/doi/10.1002/casp.2203 |journal=Journal of Community & Applied Social Psychology |language=en |volume=25 |issue=2 |pages=167–180 |doi=10.1002/casp.2203 |issn=1052-9284}} A 2019 study of sexual minority individuals in the United States found that while asexual individuals were less likely to have recently had sex, they did not differ from non-asexual participants in rates of being in an intimate relationship.{{Cite journal |last1=Rothblum |first1=Esther D. |last2=Krueger |first2=Evan A. |last3=Kittle |first3=Krystal R. |last4=Meyer |first4=Ilan H. |date=2020-02-01 |title=Asexual and Non-Asexual Respondents from a U.S. Population-Based Study of Sexual Minorities |url=https://doi.org/10.1007/s10508-019-01485-0 |journal=Archives of Sexual Behavior |language=en |volume=49 |issue=2 |pages=757–767 |doi=10.1007/s10508-019-01485-0 |issn=1573-2800 |pmc=7059692 |pmid=31214906}} Asexual individuals face stigma and the pathologization of their sexual orientation,{{Cite journal |last=Hille |first=Jessica J. |date=2023-02-01 |title=Beyond sex: A review of recent literature on asexuality |url=https://www.sciencedirect.com/science/article/pii/S2352250X22002378 |journal=Current Opinion in Psychology |volume=49 |pages=101516 |doi=10.1016/j.copsyc.2022.101516 |pmid=36495711 |s2cid=253534170 |issn=2352-250X}} and report difficulty navigating assumptions about sexuality in the dating scene.

Non-monogamy, including polyamory, open relationships, and swinging, is the practice of engaging in intimate relationships that are not strictly monogamous, or consensually engaging in multiple physically or emotionally intimate relationships. The degree of emotional and physical intimacy between different partners can vary. For example, swinging relationships are primarily sexual, whereas people in polyamorous relationships might engage in both emotional and physical intimacy with multiple partners.{{Cite journal |last1=Scoats |first1=Ryan |last2=Campbell |first2=Christine |date=2022-12-01 |title=What do we know about consensual non-monogamy? |url=https://www.sciencedirect.com/science/article/pii/S2352250X22001890 |journal=Current Opinion in Psychology |volume=48 |pages=101468 |doi=10.1016/j.copsyc.2022.101468 |pmid=36215906 |s2cid=252348893 |issn=2352-250X}} Individuals in consensually non-monogamous intimate relationships identify several benefits to their relationship configuration including having their needs met by multiple partners, engaging in a greater variety of shared activities with partners, and feelings of autonomy and personal growth.{{Cite journal |last1=Moors |first1=Amy C. |last2=Matsick |first2=Jes L. |last3=Schechinger |first3=Heath A. |date=2017 |title=Unique and Shared Relationship Benefits of Consensually Non-Monogamous and Monogamous Relationships |url=https://econtent.hogrefe.com/doi/abs/10.1027/1016-9040/a000278 |journal=European Psychologist |volume=22 |issue=1 |pages=55–71 |doi=10.1027/1016-9040/a000278 |issn=}}
