<human>: Can you condense the text into a few key points?

My girlfriend and I, both 19, I'm a guy, will have been "officially" dating for two months when I have to go back to college.  I met her off of an app and we talked for a couple weeks before deciding to meet and then shortly after to date. 

We ended up "falling" for each other pretty quickly and starting saying we love each other already.  She's a great woman.  She's faithful, sweet, and wants to make me happy.  She's also told me I'm her best friend (she doesn't have many friends other than a childhood friend she works with).
Recently, I started losing interest in her however, and the soon to be distance is looming overhead.  When I go back to school, we'll both be busy, she'll be two hours away, and we will see each other once every two weeks at the most.

My question is this: should I go ahead and break it off, wait until I find someone else I feel strongly for, or try to make it work and not lose a great girlfriend.
Thanks in advance, this is my first post.
<bot>: I'll only be able to see my girl once every two weeks after moving to college and don't know whether to keep it going or break it off.
