tell them you don't know that their girl is cheating!! Unless your the guy sneaking around with her!!!
he will be dating another girl
if shes away and doesnt tell u were she is.
To tell if a girl is cheating or not there are many ways. If you get to know from someone about cheating you should stalk her. See if there are any behavioral changes or not.
Her vag is purple.
well if you ever see him in bead with a girl that means he is cheating on you.......
I feel that my girl friend is cheating on me with some body we both know
You tell him that his girl friend is cheating on him with your ex and tell her that her boyfriend is cheating on her with your bestfriend. That will absolutely work out.
She's got an STD.
girl that can be tough and she will get mad but a sis has got to do what she a gpta do
You can tell when you r boyfriend is cheating when he starts talking about another girl a lot, when he is hanging out with another girl more than you, when he talks to another girl more, and when you catch him cheating. But don't accuse him of cheating right when he is talking about another girl because cheating isn't always the case. He might only just have feelings for another girl or has a very good friendship with her; but don't be afraid to ask your boyfriend if anything is going on between them.
Past practice, when it continues, is a good precedent. The cheating will probably never stop.
