Hi BradOCD, it’s because you love that your OCD bully knows you won’t ignore it when it fills you with doubt about your relationship, or your love for her. Remember that you are not your intrusive thoughts. If you love your girlfriend and you know it, so what if you have those intrusive thoughts, they don’t define you, just try to let them pass out of your mind as quickly as they entered it. Chances are if you left your girl because your OCD made you doubt your relationship that after you broke up that same OCD would make you doubt whether you should have broken up with her. It will never be happy as long as you respond to it. Try to tell those intrusive thoughts “so what”….so what if you have intrusive thoughts about guys or girls other then your girlfriend, they are all just thoughts you didn’t ask for and just your OCD trying to get your attention and make you feed it more doubt and anxiety. No relationship is ever perfect or free of even some doubt at some point, our OCD just likes to exploit that and make us dwell and intensify that doubt to the nth degree because it knows we most likely will respond to it because it involves whom we care about most. Has something changed recently to intensify these intrusive thoughts making you feel as if you have no choice but to leave to spare her feelings?
