He isn't going to care right now b/c he is in MLC land! He thinks he has done the right thing and that you are the cause of his unhappiness. Please don't believe a word of what he is saying right now. He is caught up in his fantasy world. Once reality sets in and it will, he will regret everything!
Don't feel bad about going off on him! You needed to get it off your chest, don't worry about backsliding-- it happens.
It probably went in one ear and out the other anyway. These MLCer's don't listen to a word we say to them. They are too self-absorbed to care what we think.
I know how hard it is to stay positive. This is something we all struggle with here on this bb. When our H's seem so adament about a divorce and never coming back it is hard to believe otherwise. RIght now you do have to look at your M as over b/c it is. He believes that he doesn't want it anymore, but it is just MLC lingo. Once he wakes up he will feel differently.
This could take years though, it will be up to you whether you want him back or not. If you choose to stand for your M and keep the door ajar for him to return. Love him at a distance. Let all of his nastiness roll off your back and live your life.
Try to keep your chin up and have faith -- let go and let God.
