Have you read any of the post on MLC? Sometimes a H who, in the best of times, is into porn, goes completely haywire when a MLC hits. Stupid behaviors will become bigger stupid behaviors, and they justify it to themselves in some way. I believe my H was going through a MLC. It's been five to seven yrs now, and some of the stuff he did, he doesn't even remember.
You do have to accept, for now, that he is just who he seems to be. It is you that you have to work on now. I don't know what sorts of friends and support groups you have, but why aren't they helping you to see that you can only change yourself, to make you the kind of W your H wants to come back to?
I can understand being angry, but you need some skills to overcome the anger when you speak to him, or you will just sound like the same bitter old W he has heard for the past four or more yrs. Pretend you are a great actress, and this is the role of a lifetime. If you talk nicer to him, and show this side to him, after awhile it will become a part of who you are. I am sure he fell in love with you when you were a young sweet girl; try to recapture that side of you that you probably think is lost.
And it doesn't hurt to pray for his salvation, I still pray for my H to want to be saved.
