<human>: Provide a brief overview of the text.

Background: We have been dating for 3 years in college, live in cities 200 miles a part during the summer, but in the same dorm building during the school year. She has been amazing to me and I have never suspected this from her at all.

So this morning I awoke to my girlfriend on her phone and when I came to my senses and moved over to her she locked threw her phone away from us. She claimed it was nothing. This ate at me though. So about an hour ago I said it was bothering me and I asked her to show me the messages over text since I was at work. She claimed she couldn't access the messages and only shows the ones that she actually told me about sending this guy. She can't come up with any of these messages sent over facebook, a messaging service I can retrieve messages from 2009 on. Am I in the right to ask her to text him to send the messages. She is avoiding this, and acting extrodinarilly suspicious. What do I do?
<bot>: girlfriend was texting another man in bed this morning. Can't get text messages from that conversation all of a sudden to prove that she wasn't doing anything.
