You're overreacting a little, but he probably shouldn't be spending new years with his friends. It's likely that there's more to it then just "hanging out". That might be his chance to see his other friends from out of the state (assuming he has any). On the other hand, he is being a jerk. Rereading your post, I'd even say he's being an ass. My suggestion is to ask him about why that night is special. If there's a reason, the you'll know it, if not, you know he's just being stupid. Either way, good luck - I hope you have a great New Year's regardless!

I don't think you're overreacting. If he sees them every weekend why would he need to see them again on New Years?
