SUBREDDIT: r/relationships
TITLE: My [31M] then-girlfriend [33F], now wife of 2 mos. had an emotional affair on me while we were dating. How should I feel about this?
POST: It just came to my attention that wife was sending nude pics back and forth with a guy for two years while we were dating. 

I found out that they had a fling before we formally began our relationship, but apparently the provocative e-mails, nude photos, and flirting never stopped.

Now we're married. I just found a bunch of pictures. It was still taking place 9 days before I proposed.

I have that nervous pit in my stomach. We've only been married two months now. I'm committed to her, I love her very much, but what transgressed is completely against my values. I would have never thought about doing anything like that to her.

Where am I supposed to go from here?
TL;DR: 
Found two years worth of pics, flirty e-mails between my then-girlfriend (now wife) and another guy. Now married, I'm finding myself in a predicament. Do I love or leave?
