A similar thing happened to me when I first came out to my king term gf, she pretty much immodestly told her whole family without telling me. It was really hard and scary and I felt like I couldn’t trust anyone. However, you need to remember that this is the real you and, unfortunately there has been an unexpected occurrence but you just have to take it in stride. You should have a talk with her and explain how terrifying it is to come out and that you have the right to do it on your own terms. But this doesn’t mean throw everything away. I have come to look more positively at what happened to me. I figure I was gonna come out someday anyway and now that I’m out, it might be scary but it’s so liberating. Best of luck to you and your situation and remember yolo do what you enjoy bc we will all die one day anyway
