Look, this is ridiculous. YES you should talk to her. Also, you need to really not give a damn about the outcome, because face it: odds are nothing will come of it. Big deal.
Then IF something comes of it, recognize that it probably isn't going to be like a whirlwind romance and dancing the funky chicken on your 75th anniversary in the year 2077. Lighten up. Way up. Just meet this girl (if you can) and lay off of all the expections.
Expectations inexorably RUIN relationships. The relationship (if any) will stay fresh WAY longer if you don't build up expectations. At first, eye contact and a word is exhilirating right? Then go for that, you know? All too soon you will no longer be filled with delight just because she looks at you or whatever. So slow down and be content. Slow down. Don't build up expectation too quickly. Enjoy yourself.
Finally, only get serious with a girl if there is something there beyond romance. Romance is that feeling you get when you find out the other person likes you, which makes you like them even more and oh my goodness will it ever end??? Yes. It does.
After romance is love, commitment and labor. You want to be with someone with whom you solve problems well. You and your serious partner should be a team of sorts, that are not only in love, but also friends with each other, and work well together. Truly.
Summation:
slow down
enjoy
resist rising expectations and obligations
don't confuse romance with true love
fall in true love with your ideal partner
