Wow WAW. I don't know what to say. It must have been extremely difficult to have to deal with that type of emotional abuse. I am surprised that it took so long for you to get tired of it. I think that your H probably did not mean any of what he said. Although there really is no excuse for him to say those types of things. You must really have loved him at some point to stick with him and still want this to work out-as I think you still do. I think you are in the right frame of mind to start to rebuid your self esteem. That is really the most important thing for you right now. You have to make sure that you get back to the person that you want to be.
Your H wants to be with you. He is just terrified of the thought that you are going to move on without him. He is not approaching the problem from the right direction. He needs to understand that if he continues to act in this manner, he is going to lose you forever. Just try and be patient with him. I know where he is coming from and it was hard for me to realize the begging and pleading was not having the effect that I desired. Now I realize it and am afraid that it may be too late.
Have the "verbal assaults" stopped? I don't see how it can work if you are still subject to that environment.
