maybe, maybe not.If he spends more time with the girl he is cheating on.
Justin Bieber has a girlfriend, if he was to kiss another girl he would either be cheating on his girlfriend or kissing said girl on the cheek.
Anything your girlfriend (assuming you are a guy) would not want you doing with the opposite sex. Basically, if you are doing something with someone that you would not do in front of your girlfriend, then you are cheating. Cheating has to do with violating your girlfriend's trust. Some girlfriends may not care if you give another girl a massage, while some may. If your girlfriend is in the latter category, then you are cheating if you do it.
it means you do not trust your girlfriend.
No, because she will fancy him maybe, but he wont fancy her! But really if you dont know what cheating is, thts scary (: Cheating is where, you boyf, or girlfriend goes up to another girl/boy and goes out with them or kisses them etc, when she/he is already out with somone else! (: xx
What if? Well, that would mean you were cheating on her. So good think you're just asking.
A cheating bi-sexual.
Whether you are bisexual or gay hooking up with another person is no different than straight people doing the same thing and it is cheating.
Here is how you decipher cheating: If your girlfriend knows nothing about it then it's cheating. If you have nothing to hide then tell your girlfriend this girl is a friend (if she is) and you're going to a movie. Hopefully you have a very understanding girlfriend. If this girl you are going to the movies with is of interest to you then be a man and break up with your girlfriend now! Cheating is ugly, it hurts your partner when they don't deserve it and it shows immaturity and dishonesty on your part. You know when you are doing something wrong!
Only if the other girl isn't hot.
He may have feelings for you, but if he has a girlfriend, do not do anything that could be misconstrued as "cheating." He has to figure out for himself who he wants to be with (assuming you like him back) and you don't want to start a relationship based on him hurting another girl by cheating.
Then i would dump him before he cheats on you with another girl. He obviously is a cheating guy so who's to say he won't cheat on you.
