Taking a break is a good idea. She is not in a good place to be part of a relationship at present. You can’t fix her. You are trying too hard. You seem more than a tad desperate, clinging to your first for dear life. You are pushing her far harder than she can stand to be pushed. From what you wrote, it is difficult to tell how much self-work you have to do and how close you are to being ready for a healthy relationship. Your gf has her parents to assist her and has asked you to back off. You need to do that. Confronting her, because of your own fears was exactly the wrong thing to do and phoning her parents to check if she returned home safely seems a step too far.
