Should I tell my friend her boyfriend is cheating on her?

Only if you have proof. Then tell her because you are "being a friend". If your friend don't protect you, why have them?
If she gets mad, let her. When she gets hurt by this bf in the future, she will look back and see what a true friend you were. It would make your friendship stronger in the end.

Yes because if shes the type of person who would rather you tell her you should because she might get mad if u dont or dont believe you at first...but regardless you were right in the end with whatever happens.

Would u want ur friend to tell u if ur boyfriend was cheating on u? Tell her

I would first confront the boyfriend telling him that what he's doing is unacceptable, and since you know all 3 of them, try to get all of them in the same room to talk. He can't lie to both his girlfriends at the same time.

No.

Yeah...unless its with you

Yes if your friendship is worth it then yeah

Youll end up risking a freind ship...but if u have proof then prove to ur freind that shes being cheated on...then tell her..show her...its the only way
need anymore help just follow me and ask
ur freind Vamp.
