You can tell by if she doesn't spend as much time with you as she used to. She won't want to kiss as much as before. She will try to avoid you as much as possible.
Try, I don't know, NOT CHEATING.
tell them you don't know that their girl is cheating!! Unless your the guy sneaking around with her!!!
Stalk her...i guess
I feel that my girl friend is cheating on me with some body we both know
If u ask her u would know.
In order to know that ask her besties they will know for sure.
You should tell the other girl and both break up with your boyfriend.
no shes not cheating but she is a lucky girl and needs to let her bf know and let him get in the action
its if he has to cancel some dates that probaly means he is cheating on you.
Well he obviosly is if he has girlfriends
A cheating bi-sexual.
Yes, first of all he shouldn't be doing that and second of all that other girl deserves to know.
