There is no sure fired way to find out, but by asking him straight out! Watch his eyes (the windows of our soul.) If he avoids eye contact or shifts his eyes (or even stares intensely ... stares you down) then he's lying. Watch his body language! If he shifts from foot-to-foot or goes off into another room. Listen to what he's saying! If he calls you stupid for even thinking that and makes a big fuss and flies into a rage, you bet he's cheating. If he just says, "Quite being so silly, I'm not cheating!" then he could well be telling you the truth. The only other signs are phone calls and when you answer no one is there. If he has unexplained phone #'s on his cell, or he's talking to other women over the internet. The smell of perfume on his clothes or lipstick marks. Bodily marks such a "hickeys" (blue bruises on his neck) or scratches on his chest or back. If he says he's taking you out, but never does and misses important events in your life such as your birthday. If he doesn't want to have anything to do with your family and friends. Check out his Visa bill and if you see motels/hotels on there, question him about it. Good luck Marcy
Ask him :/
You tell the truth and accept the consequences.
In most cases if a boyfriend was not cheating and was accused by his girlfriend then he would be angry and since your boyfriend is silent there is a high possibility he is cheating and cannot own up to it.
No. Blackmail would be if you went to the boyfriend and threatened to tell on him unless he paid you something.
Tell him the truth, say you like girls.
You should tell your friend that he is cheating its best that she knows.
Ask them!!! And if you are wondering they probably are.
Well he might make excuses to not hang out with you..
You can just tell her if you don't want her to be anymore.
He's either cheating or watching strippers
Lie and tell him you cheated on him... he'll tell you just to get even with you.
Just tell him everything.. and hopefully he will understand and appreciate that you told him.
