Please help
 

There is this guy that I really would like to get to know. We have a lot in common. Everytime he comes around, I cant think of a thing to say. So all I wind up doing is smiling and nodding. He probably thinks Im a mute.

What can I do to get past this nervousness?

Cognitive Behavioral Thearpy-
recognizing the distinct border between your unnatural fear of speaking to this cute boy and your actions. You talk to plenty of people (men) everyday who like you and respond well -- why should this one be any different?
More CBT- Practice acting confident around other people and other men. "going backwards" can help - change the way you act in ways that don't bother you so you can change the way you think or the way you feel in situations that DO bother you (or at least block those nervous thoughts).

OR

plan a good conversation and go for it!
