Should you break up if...

I am in high school and my boyfriend and I have been dating for over a year, we have had some problems with him being jealous in the past which has made our relationship a little rocky. I don't think he and I are compatible enough that this could work out past high school, and I don't want to lead him on, but not dating him is also an idea that upsets me a lot...Is it time to move on or have fun while we still can?
