So, as the title says, I snooped and found out my girlfriend (21f) gave a guy her number and she refuses to acknowledge it. 

So, my girlfriend asked me to check for a confirmation email on her laptop. As I opened it, she was already on an email, so, being the douche bag that I am, I skimmed it to check what it was and it was a personal email to (I'm assuming) one of her friends. "Number" caught my eye so I read the sentence, turns out that back in November while she was working someone invited her to a party and asked her for her number and she gave it to him, which is the third time this has happened according to the sentence.

I found the confirmation email and did what she asked me to, then when she got home we were getting ready for a movie and I asked her if she's given her number to anyone since we've been together (over a year now) and she said "No why would I do that?"

So here I am, I don't know what to do. I'm a dick for snooping through the email but I found something very sketch in my book and I feel like I'm now justified in reading the email.

Any advice?
