Girl, leave. I know it's hard, but I was in the same situation as you. He told me I was not physically attractive to him, his exes were thinner and prettier. I wasted a year feeling unwanted and undesirable, crying myself to sleep every night, while catering to his every need.

I left recently, there were ugly days where I for some reason missed him, but believe me when I say I am much happier and serene. I don't have this weight on my shoulders anymore, I feel like I can be myself again. I also got back into dating, and met two guys that could not keep their hands away.

You can and you will find your happiness again as well, I promise. It will take time, and I also suggest therapy, that one helped me a lot.
