<human>: A group of 8 of our coworkers and few friends were all planning a trip to Cuba, before we could arrange flights my exam got rescheduled to conflict with the trip, everyone is sharing rooms. Me and her have never really discussed being exclusive. Since I was unable to attend, and she didn't wanna pay for a room to herself.She's sharing a room with a guy she's always been close friends with, and that I know is into her, but she's always turned down. No cell signal while she's out there . The thought of them sharing a room is killing me even though I know that she's never committed to being exclusive. 

We have been banging for a few months , and have hung out and spent the night plenty of times. She drives me home from work every weekend. Is it fair of me to expect her to not sleep around in Cuba??

Can you condense the text into a few key points?
<bot>: 10 days in Cuba with no contact sharing a room with a longtime male friend 5 days down and it's killin me . Advice?
