stop anticipating and just be you .. have fun with out trying and enjoy each others company .. good luck
just talk to her
Write a letter and fold it into an airplane. When she's not looking, throw it at her and run. It will hit her or catch her attention, she'll read it and find it so endearing that she will dedicate her life to being with you right there. That, or you could try asking about her hobbies and making an effort to spend time with her.
why not invite her to go bowling or some other activity you excel in, that will boost your confidence and give you something to talk about.
