<human>: Last night, my girlfriend got a text from a guy at 3am, R, who she used to work with. She has in the past text with this guy a lot at the beginning of our relationship but has ceased texting with him. So, this morning I asked who the text was from, she said R. I said I want to read the text. She said that its not my business what is said in her phone. I got slightly annoyed. 

Let me take a detour. Few months back, my girlfriend saw her ex-boyfriend. She said her friend invited him over. I happened through her phone and saw that she told him to come over and then the next day texted him saying it was good to see him. I told her about it and she said I was crazy for thinking that was bad. We had a small argument about it but that was that. There were a few other instances where guys texted her things that I thought was inappropriate and she played along with it. I haven't been too trusting with her phone since that.

Back to the story, I told her that I would like to read it because a 3am text is out of the ordinary. She said he is probably drunk and she doesn't want me to read it. Again, she says its not my business what is talked about on her phone. I get even more annoyed. She finally reads the text to herself and the shows it to me. It's nothing, just him asking for a number.

Question is: Am I crazy for wanting to read a text from a guy that was sent at 3am? Is it really none of my business? I feel that her not letting me read it, saying she hates when I act crazy over texts, is a indicator that things are said to eachother that I wouldn't like. Can someone give me some light on the situation? We've been together 7 months. I don't think she would physically cheat on me, but feel that some things are said would be close to emotional cheating.

Can you give me the gist of the text in a nutshell?
<bot>: Late night text from guy to my girlfriend. I want to read it, she says no and says its not my business. Turns out to be nothing. I want to know if I really am crazy.
