Am I insecure?
So we are in an relationship(long distance me [21M] and her [21F]) for more than 2 months now and we are still figuring things out. I'm from a conservative background and trying to get adjusted to her. A week ago she asked me that she wanted to go drink with a guy (I didn't know he existed till then), i asked who is it and she said it was her one of her previous situationship, but now they are good friends, they went to drink before . I said I'm not comfortable but if you want to go you can, she asked why are you even uncomfortable in the first place my intentions are pure and she got angry that I felt uncomfortable and just said she needed a break from the convo and ended the call. Am I insecure cause I really don't know how to feel. After that I went to clear my mind. But she called me I didn't answer it because I didn't want to say things I regret. But she reached to out mutual friend and told him about the story and he doesn't see what's the issue is about. And then later me and my gf hopped on a call and I just lost my temper and said things I shouldn't have and now I am walking in a very thin line. And she still doesn't see what my problem is. She started saying that she can't cut all her guy friends bcs she is in a relationship with me. I understand but that was never my problem, my problem was that she was going to drink with a guy she had a past with. What should I do ?
