AITA for not knowing what to do with my relationships as i feel like im stuck in it?

I've been dating 17F for about 5-6 ish months and at the start it was good, going out and having fun but know i feel like she is controlling me a bit with I can and cant do. some examples is that she has a problem with most of my friends and as i am in college doing stuff she wants me to get rid of most of them when college ends, she also doesnt like it when i change my room around even though it is my room and i want to add some stuff to my car and she also doesn't like that for some reason. there's alot more like small things she doesn't like that i cant remember that much but i dont know if I can fix these problems or just break up with her but im also afraid to break up with her so my mental health and stress is just alot at the moment
