I'm going to a wedding in another state later this month, which my bf will not be attending. I'm excited to see several of my old college friends, and we have all rented out a large apartment for the occasion. Two of my exes (one I dated for about a month, another I had my only one night stand with) will be staying in this apartment as well. It would be too expensive to back out of the group apartment at this point. 

I have no attraction any more to either of these guys, and there is absolutely no chance of infidelity - I'm head over heels for my boyfriend! My bf doesn't know any of my college friends, so he wouldn't find out about the exes unless I told him. He has had several past girlfriends cheat on him, so telling him would likely make him nervous, even though he trusts me. Plus, he has made it clear that he hates talking about exes, both his and mine. 

I want to do the right thing. It seems unfair to keep him in the dark about a situation that he would certainly not be happy about, but it also seems unfair to leave him worrying all weekend over something that he doesn't need to be worried about. Is it better for me to withhold information that would drive him crazy or tell him knowing that he'll have a rotten weekend?
<bot>: Should my bf be informed about me staying in a room with exes (and several other people) for a wedding?
