<human>: I've been seeing this girl for several months [9] and is the first girlfriend that's ever really been there for me and one that I've genuinely cared about. For the last two weeks we've been apart via college. 

Yesterday I was upset because of a fight I had with a mutual friend and we talked on the phone to calm me down. I was on FB later and saw she was now friends with a guy from her college. I didn't think anything of it. I knew she'd make guy friends. We both always seemed to have friends of the opposite sex. The next day she said she was feeling guilty about something and eventually told me that she had made a guy friend and didn't want to mention it yesterday so as not to make me more upset. This is what really bothered me. She's a very flirty person, but often doesn't realise or understand she's being flirty.

 I talked to her about these jealous feelings and she proposed she just doesn't have guy friends. This obviously is not the answer and would only make me a bad boyfriend, so we came to not knowing what to do. I can't figure out to resolve these feelings. I don't believe she'll cheat on me, it just hurts to know she might be flirting with other guys and having them flirt back. 

It's also hard to deal with distance. I'm sure this is super common, but I couldn't find another post that answered my concerns. Thanks!

Can you condense the text into a few key points?
<bot>: Jealous that she felt guilty about not telling me about making a guy friend and struggling to live with the fact that I won't see her for long bouts of time.
