I had a close group of friends at the school I currently attend (8 of us and our SOs would hang out outside of school). Since then, the group has strayed, and I have stayed close with one girl (we'll call her Suzie). Well Suzie and I just found out that our friend Marcia (part of the group) has been cheating on her BF for the past couple years. She is cheating with one of the other guys in our group (we'll call him Bryan). Since yesterday, we have found out that almost the whole building has known about it for at least a year (students, professors, security guards, and others who work in the building).
Suzie is really distraught because she really didn't see it coming. I had an inclination that it was going on, but never saw or heard any proof until yesterday. The problem is that we all know Marcia's BF, and he is an incredibly sweet guy who doesn't deserve to be lied to. Suzie wants to tell him the truth. The problem is that (1) he might take Marcia's side over Suzie's since it would be her word against Marcia's, (2) if he does believe Suzie, then he might find out how many other people knew and didn't tell him.
Marcia's BF has been good friends with Bryan. They have gone on vacations together. He will probably be really upset that his supposed "friend" is sleeping with his GF.
What would you do in this situation? I'm pissed with this girl because she really put everyone in a tight spot. She's also a hypocrite because she had major moral issues with this other girl who was cheating on her BF a couple years ago.
