Address him about it face to face.
You should tell the other girl and both break up with your boyfriend.
The only way you will know if and where your boyfriend is cheating is either ask him straight out (he may lie about it) or, take a girlfriend with you on an evening he should be with you and follow him.
if you still like him and if he's not cheating on you.
ok plz tel me how do you know if your boyfriend is cheating on you?
If you can forgive your sister, you can forgive your boyfriend. It doesn't necessarily mean that you should stay with your boyfriend. Cheating is cheating and if that is not acceptable to you, you should find someone who will respect that wish.
No you should lure him to you so if he isn't he'll never know :-)
You should firstly ask your friend to be sure about that. If the friend doesn't know about that, you both should dump him.
it is not concidered "cheating" if its just hanging out, but it is very wrong, and you should let your boyfriend/girlfriend know that you are doing that.
You should tell him that you know that he's cheating on you and tell him how you feel about it. Also if he then goes hmmm... ok then just do the same back if your a bitch or if your nice then just dump them.
If you were making out with the guy or had thoughts of doing so then it is cheating and there is no excuse for cheating. If this is the case then you deserved what you got. Even going on steady basis with a boyfriend you should be honest and loyal and if you are tired of your present boyfriend then you should let him know. If you were just talking to another guy and it was completely innocent your boyfriend should have let you explain the circumstances.
Not really - one can have many friends and like those friends equally. That should not be construed as cheating in anybody's method of thinking. I think if you like someone and you have a boyfriend that your boyfriend will know or that the boy you like will know or something..... P.S Don't cheat, cheating is bad!!!
Be sure your boyfriend is cheating on you first. You and a girlfriend could follow him on the evenings he should be with you to see if you could catch him cheating. You may be able to get one of his friends to assure you that your boyfriend is or isn't cheating on you or, you could face your boyfriend and ask him if he is cheating on you. If he goes red in the face; lowers his eyes; yells and protests too much; goes into another room; accuses you of cheating or slams out the door there is a high possibility he is cheating on you. Since humans do not know their own limits 100% they can not be expected to know what another person is up to 100%.
