Lynn,

Thank you for your awesome response. I can definitely see your point.

I never heard of him before. She never mentioned him or anyone that sounded like him as a "friend". All I could see was the email communication between them, half of which was cyber sex and the rest is superficial talk. They did chat from time to time like "how is life, where are you working etc" and half of them ended with things like "I'm dreaming of you, wish you were here right now" kind of talk and dirtier.

They chatted while we were together (about 2 months ago). Nothing dirty, looked completely friendly, and he was single at the time. I think he still is, hence constantly trying to chat.

Well, I'm not picking on anyone but surprisingly I appreciate the guy, he's the man.. I read one of the emails he sent her basically saying "I'm seeing someone and things are serious with her, I would appreciate if you don't get offended because I stop talking to you". He cut her off when things are serious.

So they don't talk/chat all the time, but she did speak to him while we were together. It was a friendly chat. What does this make them?

I feel very guilty for violating her privacy, but on the other hand it's not like I dug into her inbox and found nothing but innocent emails and said "Oh what have I done".

I do trust her and I don't think she will ever cheat on me. This is the most important thing. But I can't really say that I'm 100% confident since my mind is constantly playing games with me and asking me "if she's happy with me, what is she trying to do by constantly blocking / unblocking him every 2 days on his contact list?"

The guy tells her to stop communicating because he's serious with someone and cuts her off, but my GF is struggling whether she should talk to him or not. Or that's how I see it?
