Mono, your in a good spot compared to most, you came to this board already detached, and get to make decisions that are not based on emotion.
I would suggest really focusing on you, which it sounds like your doing. Seek treatment for OCD, go outside your comfort zone socially, GAL and try and spend some quality time with H.
Your not in crises mode, so you can really take your time and see how things go. At some point, a R conversation will need to occur to see where he stands, but for now, just make changes on yourself and that may cause him to make some changes on himself. I would also recommend trying to find something that you think he might like doing with you (neutral zone) and invite him, doesn't need to be fancy, just something to experience together. Some things that come to mind, ceramics, kayaking or paddle board, 5k walk/run, star gazin (planetarium), (volunteering) houses for humanity, stuff like that.
