<human>: Can you give me a shortened version of the text?

So there's a girl I met a little over a month ago because our parents work together, and we have become good friends since then. I'm a year out of college and she still has one year left of college (a plane ride away to her). I thought she was cute the second I met her, but just acted friendly to prevent any awkwardness since we were both with our parents at the time. Since then, we've hung out quite a bit with a mutual guy friend of ours, who I am 100% certain she is not attracted to. 

The past couple of weeks, we've spent time together alone (hiking, brunch, gym, concert, took her out to lunch, etc...), however I never explicitly called it a date. I feel like we have good chemistry, and while I'm fairly oblivious to girls' signals, I feel like she may like me too. We hug often, touch each other playfully, and tease each other from time to time. She's all I've been thinking about the past week. However...

I've been reluctant to outwardly tell her I like her as more than a friend because 1) I don't want to sacrifice our great friendship, OR our parents' friendship, and 2) she is going to back to school across the country in 2 weeks.

If I don't make my feelings known to her, she may assume I'm genuinely not interested in her and find another guy while she's back at school this fall. On the flip side, she'll be back for a month in December, and told me she can't wait to spend time with me then. She also invited me to fly across the country to visit her for a weekend this fall, and I could also visit family out there in the same trip. 

Also worth noting, she is the only girl seriously on my dating radar right now, and my only close female friend. I'm really torn on what to do, and don't have much experience in these matters.
<bot>: Crush on a friend, she's going back to college for 3 months across the country, but we'll see each other again in December. Do I make a move before she leaves?
