Just say that since your a couple you should be honest if you cheated or something then tell her that if you did you can tell me but never say or accuse them of it they will break up with you if they didn't and you accused them of cheating
Just ask her.
you go and tell him you cheated on him and tell him how sorry you are and ask him to forgive you.
ask his teacher
You ask him.
dump him he cheated on you ask him why he cheated on you is it he didnt love you i loved her more get those answered first
You ask him.
think of the reasons why she cheated. for fun or maybe stress. are you two apart for long? ask yourself
The only way to know for sure a person has cheated is to see it with your own eyes. You can also ask the boy and see if he will admit to cheating.
Ask him. If he did he wouldn't admit that in public
if you have to ask your self this question its a good chance she cheated on you and its not yours.
Ask around and see if anyone knows if no one does see if he acts wierd or maybe different,or you could just ask him
It depends on why you or why she broke up with you. If you cheated - no If she cheated - maybe If you broke up with her for no apparent reason - yes If she broke with you - no
