Controlling my life

I'm 20 and my mom won't let me move out of state with family. I'm in a relationship but I don't think the guy loves me. My mom tells me all the time that she thinks he's cheating but since I want to move now, she's telling me to stay with him so that I don't leave. She's saying "stay here with him, get married, move in together, have a family"... she did the same thing when I came out to her as bi. All the sudden I was allowed to date boys and wear makeup out of her fear that I'd basically change my gender. She won't let me make any decisions for myself and its pissing me off.

I explained it more in my other post, she threatened to disown me if I left
