<human>: Can you condense the text into three sentences or less?

I'll keep this short- it's kind of simple but I just need to bounce my feelings off some helpful people. 

I really like this girl. She's very very into me as well, and we have a pretty laissez-faire relationship. She gets my personality quirks, my interests, we really click. We go to school together, but live in different parts of the city. We see each other most days, and sleep together 2-3 nights a week. I do really want to get serious with her one day....just not right now. I find myself unenthusiastic about things like spending the night with her, because I have a lot to focus on with school and I'm not currently comfortable enough with myself to share my life with another. 

She's going abroad for all of next semester (Jan-Jun) and likely will be in a different city than me for the summer, meaning I won't see her until next September. That's almost a year. I don't want a Long Distance Relationship- I never have and they just seem to create problems for my friends who are in them.
<bot>: How do I go back to being friends with a girl who I share a mutual attraction with, in a way that doesn't lead her on or ruin my future chances?
