Marriage is a state issue. However, a bill to repeal the 1996 Defense of Marriage Act has been introduced in Congress and is currently pending. It has the support of the President. If the bill passes and becomes law, then the federal government will begin to recognize same-sex marriages. Also, although states would not be required to permit same-sex couples to marry, all fifty states would be required to legally recognize same-sex marriages performed in other states and foreign countries.
I don't think you can. You either has to be single or married to adopt. Just living together is neither. if you are in a samesex relationship and has gone through partnership might be possible though.
Anyone can do anything they want to as long as they truly want it. No, in Islam having a boyfriend/girlfriend type of relationship is not allowed whether your a male or a female and whether the bf/gf is Muslim or not. If you have anymore questions regarding the matter, just ask and I'll be happy to answer them. i gree in islam having a boyfrnd or a grlfrnd is not allowd but today no youngr generation follows it .....so if a muslim girl personlly like a non muslim boy...then it is not allowd in islam.....u cannot marry him unless he accpts islam...:)
