The chief difference between Frost's same‐sex and heterosexual couples was that same‐sex couples experienced more stigma and discrimination. We discuss implications of these stressors for relationship outcomes and consider the role of attachment orientations. We also consider the imminent changes that might occur in these processes due to the legalization of same‐sex marriage in the United States. In particular, we hope that stigma and discrimination against LGB couples might decrease, and that attachment security might increase, together reducing their vulnerabilities for relationship dissolution. Legalization of same‐sex marriage should also provide new opportunities to investigate committed same‐sex relationships alongside committed heterosexual relationships.
