How should I tell her I'm falling for her?

Here's the story.

I met this girl a while ago. Since then we've been hanging out more and more. I only wanted to be friends, because we have a lot, and I mean a LOT in common. Then, her friends were telling me she was interested in me, which I could sort of tell, but I now knew for sure she did.

However, I was still set on just being friends. That is, until just recently. I'm falling for her! But I'm afraid I missed my chance and that she lost interest. How should I tell her?

Also, the semester ends in a week and we'll go different ways for the summer.

Will you be seeing each other the coming semester?

Yes, we will be.

Well, you could always just keep talking to her, biding your time til next semester... or you could try inviting her out to do something. Just be smooth but obvious that you're more than a lil into her, in the non-just-tryin-to-hit-it kinda way.
