Sam2, thank you for replying to my post.
I would be relieved if I knew that his behavior was caused by the lack of acceptance for his sexual orientation. I'm sure it would be much easier for him to deal with this, than, for example abuse.

I'm grateful to you for mentioning your friend and the feelings she had towards her sister. I was quite disturbed by his behavior but now I'm glad to know that he's not the only one doing something like that.

You've also mentioned that people molested at a young age may become promiscuous in later life. Does it mean that he might have been abused in a sexual way as a child, and that caused his sudden change in behavior now, after all the years? Is that possible? I thought that something must have happened to him recently.. But maybe I'm wrong, I'm really no good at psychology.

Like you suggested, I will keep trying to make him get some sort of help but I won't try to force him to. Still, I wish he'd tell me what really is going on because if someone had hurt him, I will make sure that this person gets punished.

I know I should be supportive but sometimes I just can't take his attitude anymore and yell at him. I even hit him once. I still feel horrible about that, I know it was the wrong thing to do but I just completely lost my temper. I was exhausted because I've just returned from work, he made such a mess in the house.. He was a bit drunk and began to talk about sex again, he was just.. trying to hit on me I guess, and no matter what, he wouldn't shut up. I apologized to him on the next day but he didn't seem to care about what happened at all.

Do you all think that I should just leave him alone now? I mean, let him skip, take the sedatives and just ignore him when he comes to my bed? Sorry for all the questions but I'm just trying to find the best way to help him.

I also wanted to apologize for my last post, I just noticed it was full of typos and errors, really sorry, I was very tired when typing.
