I'm assuming you are high school students... under 16?

That's a stupid reason to end a relationship. You didn't even know if she was still talking to him and you broke it off?

Let her go. I say this because you are really bothered by her having his email address and this will only extend the heartache if you stay together. She is probably feeling really bad too, but you both will get over it sooner if you two just let each other go and not try to stay a relationship that will not progress much anyways.

FYI: You are either a very young person like Cain said or a serious control freak. Either way...letting each other go is the best solution, imo. I cannot imagine having a boyfriend who would do such a thing or assume such a thing because I have an email of an ex.

You haven't found the real reason .. then you stop it!

It's just like a thief who didn't murder a person but the judge give him a death sentence.

Find out the reason before you act.
