<human>: I'm 22 [M] and she's 20 [F]. We've been together exclusively for 6 months but have been hooking up/dating for about 3-4 months before that. Neither of us are in school.

Short story: I was day drinking at my girl's place over the weekend and she left with her friend to get some food while I stayed behind because I didn't feel to great. I noticed her facebook was up and decided to start looking around (I feel absolutely terrible for doing this). I found a message thread in her inbox between her and a good guy friend of her's that she said she used to have a really big thing for so I read it.

There were a lot of messages from her saying how badly she wanted him to come see her and how he decided to cancel some planned visit (they live a few hours away from each other) because she had a boyfriend (me) and none of that bothered me because it was all from the very beginning of our relantionship/when we were not exclusive. Then I read one of the last messages she sent him and it was her telling him that she's very confused and that she really likes both of us and she would be worried about what happened if he did come and visit.

Why was this message more concerning than the others? It was sent to him only a few weeks after she first told me she was in love with me (she was the first to say it if that matters at all). I love this girl but I can't not be worried about this guy and her feelings for him. I'm not really sure if I should bring this up at all with her or just forget about it. She's always telling me about how she's never been so into a guy before but now I find myself doubting her.

Can you give me a shortened version of the text?
<bot>: I fucked up and did something really stupid. Learned some things that I didn't want to know (though they may not even be something I should be concerned about). What to do?
