<human>: So my girlfriend and I have dated for over three years now, both of us being 18. We made it all the way through high school from freshman year, and have generally had a good relationship. 
However, with both of us going off to college, we knew the time would come where we had to break up. That's what started all of this. Originally, we had said let's enjoy the time we have left, and deal with it when we get there.
However, on the other hand I've had my doubts about the relationship for a long time, but have always pushed them out of my mind with the though of "we've been together this long, I'm sure it's just a passing thing".
Once I started to think about the fact that this was going to end, I wasn 't scared to end it myself anymore, so I broke up with her. It's only been a couple days, but I feel better and happier. But she wants to stay together for the remaining 6 weeks that we have before we go to college. I know for a fact that I don't want to, but do I owe it to her to stick it out because we've been together this long?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: broke up with my girlfriend 6 weeks before college, she wants to get back together, I don't. Do I owe it to her to stick it out?
