You sound like you're looking for reasons to not be in a sorority. Which fraternities a sorority plans mixers with varies greatly sometimes and is a relatively minor part of being in a sorority. I barely went to mixers at all or went and stayed for a very short time. Not to mention, the boyfriend you're with now may not be the man you're with for a lifetime. Both of my serious boyfriends in college were in fraternities and they went to their mixers, I went to mine and we'd meet up after if we wanted to, usually at White Castle, where the whole greek system went after parties...lol. It isn't a huge deal.

You have until the minute before you're Initiated to make a decision. Give it time and try looking at the positives. You accepted a bid there for a reason. They gave you a bid for a reason.

ETA: A common phrase used during my new member period was "You get out of it what you put into it." I believe that pretty strongly. If you don't make an effort to give it your all, you won't get anything back. That's the way life is in general.
