Hi valexand.

I know from experience that if a person doesn't want to talk about something, you can't force them to do it. All you can do is make sure that he knows that no matter what happened in his past, you will stick with him. Just let him feel safe and comfortable to talk. If he hasn't talked yet, I don't think it's going to happen soon. Maybe in time and with therapy he will get to that place where he can confide in you. There's not much to do in these situations...
