NEVER Let Your Curiosity Hang There and not Satisfied. Don't try to block his emial access. It's no use and it may stir more of your curiosity. When you feel like to write to him, do it; and read his reply mails as before.
When you really have chance to get together (not necessarily marriage or family), do what you like to do. You will learn from life. Sometimes we have to get the truth after satisfying our curiosity.
You don't need to restraint your feeling at all. Just do what you like. Solution is on its way......
