Maven... I see the pain and sadness in your words written. Why do you think your bf is with you? The answer is: He loves you! Yes, OCD put a lot of strain into every day life... but he's with you because he wants to.
I don't know about this... if it would work for you... but singing is a good thing to keep your mind of thinking obsessive thoughts. Hard to both sing and think of other stuff at the same time. I use my writing to get things out of my mind. It doesn't work like magic... but it helps a bit.
Please know, that you can PM me any time!
