<human>: A little backstory, my girlfriend has gone on this trip before, however sometime between the last trip and now the guy running the trip openly propositioned her for sex knowing that she is in a relationship with me. She wants to go again, I told that that I would be very unfomfortable with her going due to the one persons proposition.

I trust her, and believe that she would never cheat on me, however the idea of her sharing a hotel room with this guy and his friends makes me very uncomfortable. She is upset with me because I feel very uncomfortable about the situation and have told her how I feel about it. I also told her that she can go if she really wants, I don't want to control her and want her to have fun.

Am I in the wrong for feeling this way about her trip?

Can you condense the text into three sentences or less?
