Search Results: friends pressuring my relationship

I keep getting guys saying they tapped that and they banged that in person and over text I don't know how they get my number unless through another person that has my number, I just don't know what to do, she is my first girlfriend and i admitted I was a virgin to her and I thought we were both the same because she told me she was a virgin too and that she wanted to wait until marriage to have sex, but that we may have it before if she feels comfortable enough, now all this comes out and my girlfriend said she did videos and admitted it and she's crying to me everyday saying how sorry she is, I feel insecure now about this whole thing and I just don't know what to do, she's told me that she's done these videos and that she's probably had sex with 20 guys and that she isn't really a virgin, I'm honestly really hurt and frustrated but I'm also angry and embarrassed that I have all these dudes saying they banged her and belittling me, I just don't know what to do like I said she is my first girlfriend and I really love her, I didn't expect my first relationship to be this stressful, her friends are pressuring me too to forgive her and to stop being a jerk about it and being a loser and to man up and accept it, I just don't know what to do which is why I want some opinions and help from you all cause I know how much experience a lot of people have here; what do I do?
