Should I risk it all and trust her or not? This is my first relationship and it’s also long-distance?

My girlfriend knows I have trust issues and we are in the long distance relationship. She says that she feels like I don’t trust her because I said that I wouldn’t feel comfortable with her going out to parties flying out on vacation with her girlfriends and yes, I am insecure, and have trust issues. Mostly because of my past, which was only negative experiences. I’ve told her a bit about my past, but still I feel like she trusts me fully. She said I can go out to parties and do all kinds of things, but I just don’t know what to do. I’m afraid that if she actually cheats, I will not be able to recover, and that scares me, because I have only had this one too might be the last hit. I feel like I need to trust her too fully, but my mind is trying to prevent me from getting hurt by sometimes thinking that I am single, which makes me not care what she does but that’s fake. Trust I care so much about her and I know I’m the problem. Do you think I should, risk it all and trust her fully with anything she does a risk getting hurt? What should I do? Some legit advice what is the best course of action because I don’t want to be controlling.
