is this confession like to a priest or confession to her about something you did   i also dealt with this with my ex gf i had the same thing going on and it was torture it is torture my ocd was about my ex and i felt like i couldn’t even tell her about it it ate me up inside but you have to just let it go let it win let it have its way because it isn’t the truth it’s lying to you and when you let it “win” you realize that it really has no practical influence on you the choices that you make are what’s important not what your ocd is saying to you   i know it’s painful and it’s convincing and it’s nonstop but it is a disorder that you don’t purposefully have let go your grip on it and let go
