Hello. I am Bi-Polar, and I am/was abusive, but not physically, but everyone is different. I hurt my babies mother in so many bad ways, never hit her or anything. But things I said and my actions cost me our relationship. My advice to you, is to talk to someone who is better to handle, and give advice on these situations, depending on how well your boyfriend takes good or bad news, it could be okay to leave him, or it couldn't be, because you conscious will eat you up, especially if he is off his meds, and it suicidal. Try to reason with him in a way that wouldn't get him upset, like a special treat for taking his meds, yes i know you cannot live your life giving him rewards for taking his meds, but if he does it constantly, it will become habitual.
