If you even have to ask if you should still be in a relationship because you're worried it might mess up your fun and new experiences in college then obviously it means next to nothing to you so why wouldn't you leave her? The same goes for the fact that you're asking a bunch of strangers if you should stay with a girl that you're supposedly in love with.
"Hey baby, I love you so much. You mean the world to me and I'm so happy we're together, but I don't want being tied down to you to potentially hinder the new experiences and best time of my life that I'm expecting to have next year. I mean, I really really love you, but you know, a long distance relationship would be hard and I don't want to miss out on things because I'm tied down. Plus, I might meet some new girl. I really love you though baby."
WTF mate?
Obviously this is not the consensus of the group, but again, if you're worried about it being hard or hindering your possible future experiences, what are you doing in the relationship in the first place? Unless you reevaluate this whole dumb idea, it seems like your decision is pretty easy.
On a side note, I realize that she's pretty young and that you mature a lot (hopefully) your first year off at college. If that's the reason that things don't work out then more power to you. But telling the girl you're in love with that you're leaving her because you think she might mess up your future experiences is asinine.
