This article examines the possibility that romantic love (with intensity, engagement, and sexual interest) can exist in long-term relationships. A review of taxonomies, theory, and research suggests that romantic love, without the obsession component typical of early stage romantic love, can and does exist in long-term marriages, and is associated with marital satisfaction, well-being, and high self-esteem. Supporting the separate roles of romantic love and obsession in long-term relationships, an analysis of a moderately large data set of community couples identified independent latent factors for romantic love and obsession and a subsample of individuals reporting very high levels of romantic love (but not obsession) even after controlling for social desirability. Finally, a meta-analysis of 25 relevant studies found that in long-and short-term relationships, romantic love (without obsession) was strongly associated with relationship satisfaction; but obsession was negatively correlated with it in long-term and positively in short-term relationships.One should always be in love. That is the reason one should never marry.-Oscar WildeIn contemporary Western culture, romantic love is deemed an important part of marriage. Many individuals view romantic love as a basis to marry (Dion & Dion, 1991) and its disappearance as grounds to terminate marriage (Simpson, Campbell, & Berscheid, 1986). Increasingly, romantic love and marriage have come to be viewed as a source of self-fulfillment and expression (Dion & Dion, 1991). Ironically though, it is widely believed that over time romantic love fades and that at best it evolves into a "warm afterglow" (Reik, 1944) of companionate love, a friendship-type love. How then, could something that is considered critical, if not the purpose of marrying, also be assumed to die out inevitably?Psychologists, therapists, and laypeople have puzzled over the possibility of romantic love in long-term marriages. Some have assumed that very high levels of romantic love in longterm relationships might be inefficient, being metabolically costly (e.g., Fisher, 2006) and perhaps even deterring the lover from familial, work, and community obligations. Perhaps others have been swayed by media reports highlighting the dark side of love and marriage (e.g., high divorce rates, infidelity, stalking, domestic violence, etc.). Last, maintaining the assumption that romantic love cannot last allows those with good, but not stellar relationships to maintain the status quo and avoid being threatened by the possibility of high levels of love in long-term relationships. Indeed, this is perhaps a rational strategy (even if based on a myth) given that relationship well-being appears to be significantly benefited by downward social comparison with other couples (Rusbult, Van Lange, Wildschut, Yovetich, & Verette, 2000). Or perhaps, as proposed by Mitchell (2002), love could be enduring, but in an attempt to guarantee safety and minimize risks of having unrealistic assumptions about the certainty of the relatio...
