So a little while back a friend of mine, we'll call C set me up with a girl from his second job. She will be B. Shortly after C started seeing another girl from same workplace called S. C and S aren't suppose to be together because S is a manager and C is an employee. S wasn't suppose to tell B about her and C because C didn't think she could keep it under wraps. she did anyway. About 2 weeks later C asks me if I told B about him and S. I told him the truth that I didnt, but S sure did. B got mad called me unloyal and broke up with me. Now B is calling me an asshole but I dont feel like I was. If anything I stayed loyal to one of mny close friends. I honestly think the entire thing is amazingly childish and am kinda glad B left. But AITA?
