How do you live with a narcissist?

Yikes. Living with a narcissist. I can tell you from experience that I only lasted about three months. Barely. We each had our own bedroom and then the bedroom we slept in together. But, in our bedroom I wasn't allowed to have a tv, pictures on the walls, or furnishings in the room because he didn't think a bedroom should have anything in it to distract from sleep. The bedroom was HIS sanctuary. If I wanted "things," I had to put them in my own bedroom. I couldn't have new sheets (he slept with a lot of other women on his old sheets) because the sheets were fine (many holes). I had to get our counselor to tell him to get me new sheets. Finally, he relented. He complained about my long hair getting caught in the drain, he didn't let me take the good silverware out of the house for any reason (for example, to eat breakfast on the deck), if I ate anything that would make me fat (as he was obsessed with how he and I looked physically). He would comment if I ate chocolate milk during any other time than after working out, if I ate more than a handful of peanuts, if I put salt on anything....The list goes on and on. I eventually moved out because I couldn't handle it anymore. We tried to keep dating, but eventually that ended too because his ego had taken too big of a hit from me moving out. He aknowledged that I had to move out to keep my sanity and eventually started to realize how much he tormented me....but I can't say living with him (the third woman in 5 years) he will not change and more than likely another woman will move in and do the same thing. I wouldn't advise living with one.
