He says that he loves me but that we are fundamentally incompatible, that he just wants to live alone and be himself. He said that he couldn't feel like himself when he lived with me and my girls. For example, once a week my daughters would make brownies and it used to make him so crazy he would threaten to leave. He said that it was junk and couldn't stand to see them eat that stuff and that they would get heavy and diabetes. My oldest daughter is slender and was borderline anorexic a few years ago and the younger teen us carrying an extra 10 or 15 pounds but neither is currently obese. Given that the brownies were a fun family time and the history I had with my oldest daughter's eating disorder, I chose to let them make brownies and tried repeatedly to explain my reasoning. But he felt like I wasn't listening to him. His own son smokes cigs and he doesnt stop him but my girls making brownies made him apoplectic. I know this may seem like a small example but it was huge to him. Also, he thought I was too involved in my girls lives because I would cheer loudly for them at their sports games. He thought it was unseemly but I was always just cheering and saying positive things, not talking smack to t be refs or anything.
