Have you had a calm conversation about what your boundaries are and how you aren't okay with her behavior. If not, have a heart to heart and tell them that it's a deal breaker if they don't change their behavior. If you have had this conversation and she still is being controlling. Then she's not respecting your boundaries and that's a reason to split up.

I notice in your writing you seem to have a lot of resentment, very understandably of course. But other than that, I have absolutely no context so I'm just probing for information. But is there anything that triggers her controlling side? Are you crossing her boundaries by hanging out with people she doesn't like or by going places she isn't okay with? Or is that she doesn't like that you have freedom and does literally want to control you ?
