While I was dating my current boyfriend but before we had the "Are we exclusive bf and gf?" talk with each other, I was having casual sex with somebody (nothing serious, just a fun time that I'm not proud of). After we put a label on what our relationship was, we've both been 100% loyal and committed to each other. My boyfriend's friends, however, believe I've been unfair to him (they knew he was exclusive before I was... he was exclusive from the beginning). One of his friends has even accused me of cheating. They are all girls, and have been long time friends with him. I feel terrible and have tried to mend things, but do not seem interested in hearing my side of the story. Help?

There obviously jealous, I hate girls like that.. They don't want him with any other girls, some of them prob fancy him.. Never listen to them, they see as you as the bad person and want to protect him from being hurt most likely.
