<human>: So I'm 18 and my gf is 19 and we've been together for over a year and idk if I'm truly happy anymore. We went through a couple months in the middle of our relationship that was very bad and then it's gotten better ever since then. 

I tell her I love her and everything but I know this isn't true love and she's way more in love with me than I am with her.

 I'm about to graduate college and go to a college with over 30,000 students. Should I stay with her because she's a good person and a good Christian and she's good for me but I'm not truly in love and don't see a future with her, or breakup and enjoy the next few years. 

If I should breakup with her, how do I go about it because we haven't been fighting or anything so I need advice.

Summarize the given text in a few sentences.
<bot>: dated a girl over a year not truly in love but she's a great person. Do I breakup with her or  not?
