Unable to leave alcoholic boyfriend. Need advice.

About3y ago, I met a guy that belonged to a social/mental health club that I belong too. I just spoke to him during the activities we had at club. Once a month the club also went out dinner together . One particular evening I mentioned that I was looking for a place to live, needed to move from my Sons home. He offered to rent me a mobile home, next to his house, he mother had lived there 6 y prior, before she passed. I moved there, seemed perfect for me. We both have a love for animals. So we both being single, we started dating. It was almost 2 months, before I realized he was a severe alcoholic. Had been for 30y. never had a girlfriend. As time went on, things we ok. I cooked dinner at my house. I enjoyed company, but we both liked having our own space. He was 54y, I’m 9y older. He said he drinks due to childhood trauma and it makes him feel good. I researched everything I could find regarding alcohol addiction. I started noticing things like: he acts childish, wants to watch and talk about same movies over and over. answers my questions inappropriately. Can’t remember day to day our plans. He drank during night, I didn’t see him until 4p next day. Started sending me hateful texts around 3a, calling me awful names. then not remembering them. I quit being intimate as much. He gets angry when I change things around my house, he wants to leave it like his mother had it, with all of her things. He stopped charging me rent, with agreement I would pay for any repairs needed. No problem there. But the symptoms of his alcoholism have become very difficult for me to handle. As I posted before, he had been diagnosed with several blood clots. He was told to stop drinking alcohol or he would die. Per Drs orders, and in front of him. I was instructed to remove all alcohol from his house before he was discharged from hospital. I did. Been 8d now with no alcohol. Luckily he’s hasn’t mentioned it. Now he’s more angry, harder to get along with. I’m a retired nurse, but he says I don’t know anything. He’s under Drs care. It has become totally awful to live here! I try to ignore him. I still cook, I monitor his vital signs. A part of me hates him. But the nurse in me , feels I need to care for medical needs. I’m afraid a blood clot is going to come loose and go to his heart! I would move . But my problem, I can’t afford too. Since being here, I’ve rescued a Chihuahua and 2 cats, I already have 2 other Chihuahuas. Even if I could afford to move, no place would allow to me to have my pets. So , I make myself have sex with him, trying my best to get through each day of his alcohol /now withdraws behavior. He forgot my birthday. Christmas I gave him a gift, he says, the month went by too fast. I forgot to get you a present. I get it next week. It was a back sit up pillow I wanted. Next week will never get here. We have same income. He has No bills, property left to him by parents. I love living in country, We both feed several feral cats. So I’m stuck here. His behavior last couple days , has me wondering if he has sneaked in alcohol. If I could live here, not have to be intimate, it would be better. I have no friends, no one’s allowed out here. He doesn’t trust anyone. I’m bipolar, depressed, lonely but love caring for animals. If he should die from the medical conditions he has, I would be kick out immediately, he had 1 relative, who has nothing to do with him, but has voiced her interest in his property, he refused to sell to her. So I asked him if he would make a will or statement that would allow me to live here if anything happens to him. He refused, keeps saying, if he does, I would kill him , so I could have his property! Calls me a murderer. Thinks I am going to poison him! It’s gotten Crazy out of control out here.! We need a third neutral person to talk too. Is this something a therapist would do? I’m wondering if I should have even posted this? This is too weird for anyone .
