I’ve read a lot of comments and most of them are out for blood. Listen, your brother definitely violated the trust of you and your wife and agree that you need to kick him out. However, I disagree with most of the other comments that your brother knew what he did was wrong. When people talk about the effects of watching porn and having unrealistic expectations about sex, this is what they’re talking about. Your brother needs help. If you just kick him out and sever ties and your whole family severs ties, this behavior will just get worse. I know you want to pummel him and I know you hate him right now, but you and your parents need to help him and put him on the right track otherwise I can’t see an end to this kind of behavior from him. Revenge and vengeance are easy and will not correct these behaviors. Kick him out, but please help him OP. You don’t want him doing this to others.
