I agree with Roman here. It seems like you knew that what you found out when you read the emails was going to determine the direction of the relationship. I also think that you blew the block/unblock thing out of proportion (sorry for harsh/possibly judgmental choice of words). We have all (myself included) been a little neurotic over social media or some other internet source, but the fact that you got so carried away over the "meaning" of his name on her gmail list was a little concerning. I guess this relationship wasn't meant to be if it couldn't make it through an issue of a man's name appearing on a chat list. The take away lesson from this, from everyone else reading this, is don't snoop on your partner's email/facebook/phone.
