My roommate and family are awful and im trapped, what do I do?

Theres layers to this so bear with me.

I(24f) have lived with this roommate(27f) for about a year now. My mom made her move in with the pretense that she’d help me with rent, which I don’t need help with because I don’t really have to pay much and I own the place in name, but my mom payed for it. Before anyone says anything, my mom couldn’t put the place in her name when she lived here and forced me to do it, then ran away leaving me with a whole lot of responsibilities making it hard for me to leave.

Roommate was nice to live with, friendly, didn’t mind cooking and cleaning, and knew my family pretty well even though I’d never heard about her. At the time I was working two jobs and didn’t have time to breathe so I didn’t think much of the family thing. Until for whatever reason, she told me she had been seeing my uncle(don’t know his exact age but he’s in his late 30’s). My uncle with a girlfriend and kids. When I stared at her blankly wondering why she’d even tell me that, she told me they stopped seeing each other the year prior because he was two timing the gf and her. I left it at that and felt very uncomfortable with the relationship she had with my family, all which my mother knew.

Fast forward to my uncle cheating on his gf with my roommate and getting found out by the gf that things started to blow up. I didn’t want part in it and told everyone to fuck off, and told my mom to kick her out if that’s what she wanted. Which she didn’t, and I just decided not to be a part of that despite being really close to my uncles gf(which I’ve felt guilty about since it happened) and so my roommate stayed.

I voiced a few times I wouldn’t feel confortable with my uncle being over, and that has been done twice counting today. First time I didn’t know about until weeks later because she let him in while I slept and he had been drinking. I told her that wasn’t ok and to at least ask.

Today he came unannounced, and I actually think she knew about it beforehand because she deep cleaned the whole place when she usually lightly cleans on the weekend. He was also drunk, and I gave my roomate a look telling her not to let him stay and she didn’t do anything, like at all. I told my uncle if he was staying he’d have to stay in my brothers room. Which he didn’t listen to me at all and went straight to my roommates room. I was taught to respect my uncles and whatnot so it was really hard for me in the moment to try and kick him out, especially because he’s family, I’d let him stay any other time if my roommate wasn’t living with me.

Regardless I feel extremely disrespected, uncomfortable and very disappointed. Not with her because she’s lowkey very delusional and I didn’t trust her anyway, but with my uncle, because why would u go to your nieces house while ces house while she’s there and sleep with her roommate.

I called my mom to tell her about everything since my uncle lives with her and she laughed at the situation. And I was very angered by the way she was handling my emotions, I told her I wanted them both gone. Then I realized things like these were going to keep happening as long as I lived here. But the only way for me to leave is to sell this place and run away.

I don’t know what to do. I want to kick my roommate out, she’s under no contract and just pays me half my rent. I also want to just sell the place and leave, but the process sounds so grueling especially since I don’t know anything about that stuff. I just hate that they feel like they can walk all over me I just don’t know what to do anymore. Any advice would be greatly appreciated.
