2. You are (?way too?) jealous when it comes to her being alone with other men when you're not with her.

The first possibility is based upon your post, the second is based upon my general knowledge about how a lot of guys would feel, not saying that this is the case with you, just that maybe you should consider it.

The only way you're going to find out the truth is to talk to her, don't hide why you have your suspisions, tell her the truth, bring up what happened at the party, your coming across the emails to her from a guy you've never met, ask her why she has lied to you about what she has been doing, and so on and so forth.

Talking to her about this could help to fix problems in your relationship that you aren't even aware exist right now, or it could help you realize that the relationship just isn't working out and that it needs to end, or you could find out that she is cheating.
