Advice on inlaw situation..

My brother in law was married for ten years and was on medication for his anger for the last five years. No he never hit her or called her names, he was just mad. He went to therapy, tried different drugs and nothing helped. Then one day I asked him a question, I said,, ever think that you should be angry about something?
He had never thought of it that way. She treated him like crap, was lazy and cheated at least five times that he knows of. Hell dude, you are supposed to be mad!

The point I'm trying to make is. Don't apologize to somebody that treats you like $&;@! They should be kissing your butt to make amends, not the other way around.

And congrats of the kid...
