Cheating girlfriend signs. These are the one you should get. I agree to some extend with you mate, but not completely. Me and this girl were technically not together but we were talking; I guess shed gone out this night and went to a frat party. C'mon be smart unless you are just as helpless as they are. You have to be crazy! I hope, next time, I can spot the signs before its too late. My lack of trust for women made it easy to cheat for a while. Then think, would you be happy with this man? Before you embark on your mission in finding out the truth, take some time to consider what you would do if he was cheating.
