I don’t know what to do anymore

My husband and I got married this past April, we met in 2018 (his mother lived across the street and sent him to meet me). My family except for my daughter (lived with me then) have never met him, because he has a past. He’s been in prison and when he met me started turning his life around as he didn’t want to be that person anymore. We were together 5 years before we finally got married. Before getting married going on 3 years now, his mom who has dementia (as far as we know). Has moved in with us! Reason I’m saying this is because she’s faked a hell a lot! Her and her husband are separated and he lives in Florida said she was at like 80%fake and 20% real when he came to visit. She had 4 kids total including my husband. His mom has already went through 2 of his siblings and the last one broke down after the called every day for like 3 months solid. Back story, she emancipated my husband when he was 15, he overheard her tell the judge that my husband was a mistake and never should have been born. My husband whole family are just pieces of crap. The older bro refused to help him when he went for help getting off drugs. The baby of the family and the sister are alcoholics. The stepfather ( that doesn’t want anything to do with the mom or even take care of her. He’s elderly and sick too. Due to his upbringing or lack of, he caters to his mom ALL THE TIME! We have never fought like this when it was just him and I we argued but never like this. It get heated and then he starts breaking crap all yelling , cussing at me and calling me names (bitch, lazy, fat ass) we fight and argue very passionately. Anyway now his mom has resorted to putting out cigarettes on whatever she freaking feels llke. I have never been in home health care but when her getting sick he said he would not allow her to go to a nursing home. But now she pews and craps in the bed refusing to get up. Then claims she doesn’t know what happened! She has thrown her hospital tray at me but he doesn’t have any empathy or compassion towards me anymore. With me if I’m hurt or sick he can’t seem to cope on his own. I feed her, bathe her, clean all these messes up. He has also accused me of cheating on him for the last 3 years all, faked a heart attack. I have to disinfect the bathroom with bleach and it takes me an hour or more to clean her room and the guest bathroom! He starts bitching at me before we eat ( then I’m not hungry anymore) and right before sex. Which then I’m so mad, hurt, emotionally hurt and mentally exhausted I don’t want to! He doesn’t get it at all it seems🧐🧐🤨he starts threatening to destroy the house which means breaking a ton of shit leaving it for me to clean once again. We’re newlyweds and I feel like I come 2nd to everyone and everything!!!! We didn’t even get a honeymoon night because he promised his friend which was in our wedding! They stayed gone all night long! Me? I was at home taking care of his mother. No one in the family wants this woman and have to takeof her. I told him if she doesn’t go soon we would not make it. He’s my soulmate, everything you can meant in a relationship but when he’s around his mom he isn’t that person anymore. He has guarded his heart so long he easily goes right back to cold, and heartless except with his mom and his dog. Cleaning he up is becoming every day now and I’m not a home health aide in any way. I love my husband with all of me but I can’t take the accusations, the being left behind to take car is his mom and the verbal abuse anymore. I don’t know what to do anymore or how to get past this or make him understand. I feel like he’s being the bad version of himself to make me choose and we have some legal issues that we have to take care of and we are beyond stressed!!!! Please help
