<human>: So this happened almost a year ago (we have been together for 2 years) and I still feel sick when I think about it.

I snooped in his e-mail, I know that was very wrong but it started as an accident, I went to check my g-mail but it was logged into his account. I saw some e-mails (old dating sites, he was not on them anymore, but was still getting e-mails from them... I told him that I had seen them and he cleared it all up with me so no issues there). The problem is I got so insecure that I read more of his e-mails. Which is where I found this conversation.

He was talking to one of his close friends and he described me as being  "not as naturally beautiful as (ex-gfs)" but further in the conversation he said that he thought I was perfect, just that I wasn't quite as good in the looks department.

To be fair, I've seen pictures and they are all really stunning. But when he calls me beautiful now I just feel like he is lying to me.

Can you condense the text into a few key points?
