Once upon a time very long ago I was married to a guy like that. At first I couldn't figure it out. It started several years after we got married. Well I left because I don't enjoy fighting or arguing or defending. Not my cuppa tea. Why are there folks who seem to do better amidst strife and discord than they do when life is just a bowl of pitless cherries? Psychologically what is going on? Do they think they don't deserve being happy?
