The researchers found that LGBT participants who were married reported better physical and mental health, more social support and greater financial resources than those who were single. “In the nearly 50 years since Stonewall, same-sex marriage went from being a pipe dream to a legal quagmire to reality and it may be one of the most profound changes to social policy in recent history,” said lead author Jayn Goldsen. About one-fourth were married, another fourth were in a committed relationship, and half were single. Married respondents had spent an average of 23 years together, while those in a committed, unmarried relationship had spent an average of 16 years.
