My SO has OCD, she's not seriously impaired, but enough and in a way that has serious consequences on our relation. She did not talk about it as soon as she couldn't restrain herself in my presence, and then she progressively introduced all her compulsion of everyday. I don't mind it much by itself, but it brings serious interference between us. Beside the bearable fact that it's slightly annoying to see someone having short but unexplainable behavior in your presence, sometimes I have to repeat myself because she can't understand what I'm telling her while she's in the middle of a compulsion, or sometimes she's blocking my way, and won't acknowledge my presence to let me get through. It's often hard to accept that my immediate existence as a human being has a lower priority in her brain than her irrational compulsions. It sometimes drifts into a feeling of betrayal, since she never talked about it before we were committed to each other. I don't blame her, she was very ashamed and genuinely though she could temper her compulsions for me. The other problem is that I can't talk too much about it, since she can't help it, she always at risk to build up more guilt, and with no possible release, ends up with more stress. And for someone with OCD, more risks of irrational fears and then compulsions. Vicious circle. I had a lot of thoughts on the subject, and to me OCD really looks like a dissonance on processing reality, and control of it. To me anxiety is mostly a feeling to push the brain into anticipation of the future, a stimulation of intelligence to solve problems like having a safe shelter or ensuring food provisions for the days to come, to control the environment. This requires to understand your environment, and trust this understanding to feel safe and stop anxiety. My theory is that people with OCD have difficulties to feel that safety, and combined with some anxiety they have the urge to interact with their environment to satisfy the brain with its need of control of the environment. But since there is nothing to do for immediate safety and control, something totally irrational is built from the ground up, for the sole purpose of doing something, and satisfy the brain.
