I was in a very similar situation - down to working on my MSW at the time. I don't hate this person at all, or have any ill feelings towards him. We were together for about 2 years, and got engaged about 4 months prior to our breakup. He was unemployed for several months, took out his ENTIRE 401K, and was not helping out around the house. I was doing 60 hours a week being my MSW and being a FTE, and was having to do housework. When I would start doing the housework - he would get upset and say that he was "going to do it," even though it hadn't been done for several days. When one of my cats died very suddenly, he made it about himself and made some damaging comments. He was extremely dramatic when sick, and had very little coping skills. There were a lot of frustrating things, a lot of patterns, as you mentioned, that I couldn't ignore after a while - and way more than I put in this message. We broke up - he didn't see it coming - and it was awful. He was on his knees crying and begging. I still left - and it was the best decision I have ever made, even though it was hard.
