I say kick his @$$ to the curb.
My ex (who at that point I had dated for like 3 or 4 yrs) wanted to break up with me the NIGHT BEFORE MY INIATIATION b/c he didn't want me to join my sorority. I said, "Ok ... thanks, you can leave now!"
Don't let the door hit you on the way out, buddy.
Yeah, I was sad, but my sisters were there for me. If he was going to dump me for something like that, to hell with him
