it breaks my heart to read "just emotional abuse" as if you are discounting it or making it not a big deal, abuse is abuse, and it's damaging and it's wrong. i agree with others he needs his own therapy. and this is just my opinion i'm not an expert or anything but it sounds to me like him wanting to come to your sessions is a way for him to make the emotional abuse your fault or something. instead of admitting he has a problem and seeking out his OWN therapy. what a dreadful situation. I'm so sorry you're going through this and I'm sending all kinds of good thoughts your way.
