Possessive? Weird?

When my boyfriend says stuff like this it hurts me a little and i find it weird. Does anyone else find it weird?

He also doesn’t “allow me” friends. And i “can’t” talk to other guys and let them touch me. He says i’ve always been his and tells me i should always be loyal to him, even before him. He asks the same questions over and over almost every day and my answer never changes. They go like “have you always been mine?” “have you always been loyal to me, even before me?” “Has any other boy touched you?” “Have you ever had another conversation with a boy?” “Am i your first everything?” etc. If i don’t answer the question correctly he will make me say sorry and if he doesn’t like my answer he will get so pissed. He even thinks me getting molested by my younger brothers friend is my moms fault and calls her a bad mom because she told the boy he can come in my house to play with my brothers. He forces me or guilt trips me into sex. He’s so weird. What do i do. I’m 15 & he is 20.
