Dealing with someone who's narcissistic, bipolar and an alcoholic is one of the hardest battles I've ever encountered in my life. I'm at the point of believing that what he says is true. 
I find myself questioning myself. Everything that goes wrong or can go wrong, I am somehow the blame or connected to it, including the things that he selects to do. If he sits in his garage all day and drinks, I'm the reason he does it. If he chooses not to work, it's because he's tired because I rather argue with him then be supportive. Mind you, I'm woken up out of my sleep at 230 in the morning, to be told that I'm not the woman for him and how any decent woman would know whatever blow he's throwing at me at that moment. I'm tired and literally at wits in and still trying to figure out this dead end marriage. I sometimes know what I want to do but there's a lot of things factored in that won't allow me to just walk away.
