*Points up*
I agree with Sharky on everything mentioned.
And I also want to add, I understand that you're afraid to get rejected,
But just think of how you'll feel if you don't at least try and open up to her,
You might find yourself thinking, "I wonder where we would be if I would have taken the chance...'
Whenever I back away from pursuing relationships, I find myself regretting it, and it eats me up.
Whatever you decide to do, good luck!
