<human>: Can you provide a brief rundown of the text in within 3 sentences?

Ok so I'm a M 19 years old..and my gf is 18. Quick background. We've liked each other for about 2 years now, been officially together for almost 2 months. I live out of state for college so I barely get to see her..here's the story!

The other day, she had a few friends over at her house (remember I'm still out of state) I found out there was one guy there. This kind of bothered me at first but I thought maybe one of her friends likes him or whatever. Next day, I see they've talked a bit on FB and what not. So as the really jealous person I am, I need some advice. Am I over analyzing things? Should I just try extra hard to make sure I don't lose her? Cuz right now I'm feeling so jealous that I'm distancing myself.
<bot>: My gf has kinda been talking to other guy. I'm jealous and distancing myself. Should I try extra hard to keep her? ADVICE PLEASE
