so sorry he does really need you but what I think is by no means make me right. It sounds like he takes his anger out on you by doing the things he knows brings you down and that makes him feel good but he is the victim and makes you feel guilty but really your the victim and if and when you decide to divorce you will have a hard time but in the end the more your away from him your head will start to clear and you will see the truth. I could be wrong but it's the way I see it sorry
