He did not really realize he had a problem

I was in a relationship for a couple of years with a man that had OCD. He was only eating junkfood and had a lot of little tics for example when opening a door, walking on tiles etc.

Eventually I left him, because I had the idea that he was not going to change. He himself did not really realize he had a problem.

I did not want to suffer from his problems, and I am very relieved that I can think about myself again and not have to be busy with him all the time and the problems he caused.
