<human>: My girlfriend and I had just moved into a home together recently and things are great between us. Recently I've been assigned to a job out of town, and while I'm gone she is having two of her friends stay with her, one male, one female. 
I have met the guy briefly once, but never really got to know him. They have had experiences in college together, but that's as far as I know. She says they are strictly friends at this point. The other friend, (girl) is not dating him. 
Anyway, she told me they were all having drinks and watching a movie, and planned on passing out next to this guy on the living room floor. Which bugged me more than it probably should have.
Now I do have tendencies to be insecure and jealous, so I'm really trying not to make this a problem, but at the same time I've been burned by cheaters in the past, and I fear that if I speak to her about this, it will make me seem insecure and lose her attraction. What would you do in this situation? Should I tell her that I think it's inappropriate? Or is it completely ridiculous that I'm stressing out about this?

Can you give me the gist of the text in a nutshell?
<bot>: Girlfriend has friends over (one guy one girl) while I'm gone, they have drinks and watch movies together, GF tells me that she is passing out next to the guy on the floor. What do?
