I am a totally confident young lady...until confronted by someone I'm attracted to.

Then I start tripping myself and anyone in a 50 ft radius, stuttering, blushing, and otherwise feeling like it's my 1st day in my new skin. I don't know why- I just get SO nervous!
Eventually I do come around and hopefully he's still there. That's the most important part for you- PATIENCE. If you really think she likes you than just move slow and she will relax.
Trust me -we shy gals are pretty cool once you get to know us.
Good luck!
