Hey bswc,
I had a nasty breakup with my girlfrend last year (also same sex relationship)and was kicked out of the house. It was not abusive so I can't imagine the hell you are going through, but there is still pain there.
This does NOT sound like your fault sweety, you are obviously a sensitive and thoughtful guy.
Emotions are raw right now, yeah? I hope you have someone to talk to or are getting help finding someone to help, because you are hurting and you don't deserve to.

I'm wishing you some peace and space to work yourself out. Be gentle to yourself ok?
