I am not sure how common this is, but I have false memories with my OCD and it usually revolves around the time that my boyfriend and I were long distance (together 4+ years, we used to be long distance 2 years ago). I worry that I did something terrible to him and don't remember. I know I never cheated on him physically (something I keep having to remind myself, since my mind will play tricks on me) but I worry that I flirted or crossed the line otherwise. I have no real specific memories of flirting or being suggestive, only memories of speaking to men. I keep confessing to him and apologizing "just in case" I flirted, but honestly I don't remember doing anything out of line. This fear really impacts my good times I have with my boyfriend because I keep worrying that I don't deserve him.
