*hugs* Im soooo sorry.
I dont know that anyone can tell you when the pain will stop. I have been seperated 6 months and it still hurts, I still get lonely and think about him. I have not spoken to him in a month.
The only advise is what everyone here will tell you... take the focus off him and put it on you and your kids. Time is the only healer and dont worry about what he is saying, remember he is not in his right mind, he is sick and there is nothing you can do to understand it. Trust me I have tried.... it will drive you nuts. Please remember that in taking care of you.. its the best medicine.
