Superstar,
A person who has nothing to hide, hides nothing. When you enter into a marriage, there are no secrets. Privacy is not the same thing as secrets. And he is being secretive. If not, why change the e-mail password. He betrayed your trust. Now that trust needs to be earned back. And he's not doing a very good job at earning your trust back.
If he is this secretive before you get married & he will not do anything to become trustworthy again, then marrying him should be out of the question. If the problem isn't dealt with now, it will only get worse once you're married.
He needs to show you that e-mail that was sent about not contacting him again. He is still trying to keep this going, I'm afraid. I pray that's not the case, but it really sounds like it.
