I'm not surprised you feel overwhelmed, Blusea. It IS a lot. Most relationships would not survive that type of behaviour.
Perhaps it would help to bear in mind that it is your husband's job to repair the damage he has done and work on himself so he does not do it again. I think that's why Steve85 is reminding you to concentrate on actions. His actions, not yours. You can certainly require a great deal from him before committing to him again if that is what you want to do. But it isn't your job to do the work.
