I need positive words?

Ok so my son father never really talks to me like that when he’s home. He goes straight in the bathroom to smoke and get on tik tok he will not talk to me like he use to do I finally had enough and just told him I wanna be by myself and I want him to leave but he says he pays rent and that’s pretty much while he’s here…. He’s physically and mentally draining me so I’ve had enough! I’m renting him a rental car under my name and insurance and he gets drunk and goes to the game room and loses his money then gets mad at me and doesn’t want to pay for his rental car. I’m so mentally fed up. Any good advice for me please
