My boyfriend (let's call him L) is really struggling with (undiagnosed) OCD. He wants to admit himself to a mental hospital in the town we both live in. The mental hospital in our town is really bad, I had a friend who just about escaped from there and my mums friend who used to work there had to quit because of the way the patients were being treated.

He hasn't even tried one on one therapy, group therapy or any kind of therapy yet even though I've told him he should try that before admitting himself. Hell, he isn't even diagnosed yet (it's clear that he has it and he has all of the symptoms). I've told him he needs to get diagnosed and get therapy but he is insistent on admitting himself even though when he goes in he will lose contact with me, his friends, what healthy coping mechanisms he has left and his pets. I told him locking himself away from everyone and everything he likes isnt going to solve anything, why isnt he going to try getting help outside the mental hospital where he can still do the things he loves and maintain a relationship with me? 
I want what's best for him but I'm feeling so conflicted, my bpd is really bad at the moment and I feel like I'm being abandoned. He's the first person to know about my bpd, I've only just been diagnosed and now I'm losing him too. It feels like I'm losing everyone I care about and that the others are just trying to find ways to get away from me. I have 'friends' but hes the only one I actually have if you get what I mean. While hes in there he isnt allowed a phone and I'm not going to be able to cope on only being able to see him once a week, if that. Everything is falling apart
