<human>: We dated for most of college (2 years), broke up on good terms (just weren't that into it any more). We don't really hang out any more, but we text frequently. I am on a ski team and we have an annual ski trip every New Years where we rent a condo for about 50-60 people and we all party and ski together. Guests are totally welcome, but my ex has expressed a lot of interest in joining in. He has one good friend on the team other than me, but isn't that close with anyone else. He wants to bring his high school friends, too. 

I don't mind hanging out with him, but the New Years trip is always full of shenanigans. You put 60+ college kids in a 2 bedroom condo and shit always goes down. Therefore I don't really want to be in that situation around him. He really wants to go because he has gone on previous years and it's a great time, and he keeps telling me how excited it is. I don't have anything against him, but I don't want to get back together or anything. I still would rather not see him hook up with one of my friends. 

So should I tell him not to come? We have been nothing but nice to each other since the breakup so I feel like this would come off a little mean. Should I tough it out?

Can you condense the text into a few key points?
