how do i deal with a live in bipolar boyfriend, please help!?

If you could take the time out of your day to fully read what I am about to write, it would be greatly appreciated. I am a single mom seeking serious guidance in a scary situation.

My toddler son and I moved out of state to be with a man and move in with him. He was diagnosed with bipolar disorder about 7 years ago, which I was aware of, but he was medicated, off of alcohol and doing well. We moved in about two and a half months ago, signed a lease, and settled in, to find out that he had decided to come off of his meds. Things have gotten just worse and worse. He accuses me of cheating on him all the time, he breaks into my electronic devices to read my stuff, and he has started drinking again. He is having severe, textbook manic episodes. Monday night, it got really bad. He locked me out of our bedroom and wouldn’t let me in and we got in a huge fight and I told him to seek help or we were leaving him. He was screaming about how he is invinsible, king of the world, government consipracies, and the list goes on. He kept me up all night and literally wouldn’t let me sleep. Yelling, telling me I don’t love him, so on so forth. Monday evening I contacted one of his family members and let her know what was going on.

Tuesday night my son and I came home and he had been drinking again, same manic attitude. When I put my son to bed my boyfriend Urinated on our living room floor because “he felt like it”, smeared it around with a towel, and threw the towel on top of my sons clothes. I was the one who actually cleaned it up. Then when I attempted to go to sleep he started singing a song (yelling) that he was going to kill me, kick me in the gut, to get out of his house “stupid-bit**”, etc. Wednesday at work I sent him a text and told him if he didn’t get into the doctor that day, we would not be home. He didn’t go to the doctor, so I went to stay with one of his family members in town, but did not tell him where I was going.

I told him a few weeks ago I would pay his school tuition, but I told him this morning that I am no longer paying it, because I am not helping or investing in someone who won’t help themselves. He is upset that I backed out of paying for his school, but why would I do something generous and loving, when he has emotionally tortured me for the last two months.

I do admit, that I have lost it a few times and yelled back, and I even punched the wall on Tuesday because I was so upset. I haven’t slept in days, my son is confused and upset, and so am i.

He is really upset that we aren’t coming home, but I can’t put my son in danger, and I feel like I would be if I went back before he gets help. His family has all taken the time to speak with me, and his Aunt and Uncle are letting me stay with them for a few days until things cool off.

In the meantime my son is really ill with pneumonia and an ear infection, our actual apartment is undergoing water damage maintanence, and my family is supposed to come into town next weekend. I am at a loss here guys. I don’t know if he is going to get help. I am stuck in a lease with this man and he has gone off his meds and off his wire.

Please, any advice is needed.
