Well, we try to help each other as best we can. I hope you and your boyfriend find the help you're looking for.
Thank you for your responses. I have found this forum very informative.
See if there is anyone else he knows who can encourage him to seek help. What he has potentially sounds like bipolar but only a psychiatrist would understand it in full but sometimes emotionally manipulative behavior can be part of a psychiatric disability but you still should not have to deal with but it might improve with treatment. If other people were supportive of the idea of him seeking help it might make the difference.
Well, we are not doctors so we can't say for sure. It sounds like a lot of things. It could be bipolar but it could be something like borderline personality, or even other things, or a combination. It does sound like he has depressed episodes, hard to tell if he is having mania, though. It could even be the worst, that's he's just controling and abusive. (Although I hope not.)
I would say the worst thing here is he refuses to see a doctor. The only person who can help him is himself. Until he does something that forces him to see a doctor, which is usually a terrible thing like suicide attempt or hurting someone else, then there isn't much you can do.
I just hope you're in a situation where you can find a safe place if you need one. I'm sorry. :(
