<human>: So I learned yesterday that my girlfriend of two years is staying in a hostel in Rio de Janeiro with two of her male friends from college. She had traveled with them previously before, albeit with a much bigger group of males and females. 

She has traveled with one of these guys in the past during our relationship but had one of her female traveling friends with her. She also asked me if I felt alright about it to which I replied yes.

This time she had told me she was going with some of her friends, including the same male friend. Honestly there is blame that lands on me for not asking exactly who she was going with, but I had assumed it was going to be the same crew as the last time as she didn't bother to ask me how I felt about her going.

Yesterday when I asked her who she went with, she told me two guys and one girl is "supposed" to meet them there. As of today I haven't heard anything about that girl. I emphasized to her that I trusted her but I also didn't like the fact she was thousands of miles away in Brazil with two men completely unknown to me. I have no idea how these complete strangers feel or act towards my girlfriend.

She immediately blew up saying my insecurities ruined her trip, how she was embarrassed and hurt I would think she would cheat on me. It took till the next day for her to acknowledge she overreacted but is "still upset".

I trust her, I have no reason not to trust her, and I know she absolutely loves me. I'm not sure what it is, but I just cant get over the fact that she's there with two guys. I know if I fought her about going on vacation with her friends she would get pissed for thinking I don't trust her.

I trust her, trust she wouldn't do anything, but I don't know why I feel so horrible about the whole situation. The fact just two guys are there changes it entirely for me.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Girlfriend is on vacation with two males. I trust her, she took offense to the fact I considered it inappropriate and weird. not sure why I feel so anxious and bad about it.
