He was foolish to tell you about all his money, because half of it is yours.
Anyway, in all seriousness, I think its easy to say the things you are saying when you are angry, but much more difficult to carry through. I'm not doubting you at all, I just think it is reality. Based on what you shared here, its not a healthy situation for one, and it sounds like he's "pushing" you to move on. So call his bluff, or make him happy. Win-win for you. No one needs that kind of verbal abuse. Life is too precious. Keep us posted.
