i've been going out with this guy for like 6 months now and i suspect that he is cheating on me because he doesn't spend much time with me. it seems like he is avoiding me and everytime i ask him where he has been he avoids the question and gets mad at me? are these sigs that he is cheating on me? i mean, how can a girl tell if a guy is cheating on her? does any one here have any expirience where a guy cheated on her?
