Telling parents about BF

Elizabeth
I'm getting back together with my boyfriend. He's broken up with me two other times this year and we've ended up back together both times. About a month and a half ago he ended it again. We've been talking a lot about it and decided we're going to give it one more shot. (I don't want people telling me not to. However, you have full permission to say "I told you so" if it doesn't work out.) I'm going back to college soon and then we're going to be officially back together. I said something to my mom about me wanting her to meet him and she went off and said it wouldn't be worth her time. I don't want to hide my relationship from my family but at the same time I'm scared of what will happen if I tell them. What do I say/do? I might wait until I leave for school but idk.
