<human>: We've been together for a little over a year.  My girlfriend is only friends with guys.  Her reasoning for only having guy friends is that girls just cause a lot of drama.  Is this a valid reason?  Anyway, she met this one guy a few months ago while she was on vacation and they have been getting closer and closer.  I have never met him.  Lately she has been distant and it started after he visited her and spent the night, which I didn't think much of because he lives a few hours away from her.  She did not tell me that he spent the night.  Because of the distancing, I felt insecure and snooped a little.  I know she deserves her privacy, but I really do not feel good about their relationship so I snooped some more.  She refers to me as "friend" or "buddy" when she talks to him.  She took her relationship status from facebook off.  From being in a relationship (without tagging me [I had mentioned that it bothered me that she never wanted to tag me in anything and it made me feel like she was embarrassed by me but she never did anything about it]) into not having a relationship status.  They have mildly flirty conversations with each other and even use kissy emoticons in their conversations.  She went to a drinking party with him yesterday and she's not home yet.  Is it unreasonable to conclude that she is cheating on me?  Do you guys think she is?

Can you provide a brief rundown of the text in within 3 sentences?
