I work with a guy who went through something similar. He is ok now, very out and happy with his orientation but still will talk about it, and when he goes home for holidays they still are unaccepting. He's 40 something and they still have not come to terms with his gayness.
My daughter's girlfriend literally started crying one day "you guys are so accepting of me" she practically lives here because her parents are not. WTF, parents? I don't get this. I live my straight lady life, their lives are theirs, their sexual orientation has no effect on me, unless they like assholes, which they do not, all have great boy-or-girlfriends.
