I agree with Bagheera on this one. Your wife sounds like the girl in the Exorcist as the priest was getting closer to success. The only thing missing is her head turning all the way around...
From what I have read of your situation, I don't know that there is any hope for your marriage or not, but I think you need to proceed with becoming Mr. NotPathetic for another reason. Assuming your marriage ends, do you want to look back and be ashamed of not being the man you could have been? Also, if it does end, if you don't fix these self-esteem habits now, you are going to likely end up connecting with another woman who will treat you crappy and let you be Mr. Pathetic in your next relationship.
Either you save your marriage by changing your ways, or you re-enter the single world a better man. Either option is better than continuing as Mr. Pathetic.
