Should I stay with my boyfriend till grad?

Our grade 12 graduation is on the 24th, so just over a week. We have had a rocky relationship (a lot of fights, drama, and lies) and I seriously don't feel like I can take it anymore!!! I knew it wouldn't last after grad about a month ago but I was going to tough it out so we would both still have dates and have a happy non-drama night to remember but it has been so hard. He's really jealous and he works with these bitchy girls that I don't get along with and they told him I'm cheating and I'm not so he's freaking out and wants to beat up my friend and I am just so sick of it!!!! I didn't do anything wrong yet he still listens to them! Ugh. Anyways if we break up now we're going to have a hard time finding dates plus we match perfectly already and it's too late to buy a new dress/tux and we have a $70.00 corsage and boutannneer ordered that much us.. but I seriously can't stand this drama anymore! I'm so over it.
