I have a similar story. Me and this guy I met felt extremely awkward around each other. We couldnt talk on the phone because it was so awkward. Then things started to go downhill. I had met him through a friend. Then I realized that I really liked the guy and I was determined to make this work. My determination of keeping up conversations and slowly adapting to this new sense of feeling (love) eventually led to him asking me out. Im in high school also. This guy is my first boyfriend and we are still together. We have been dating for over 10 months

now it sounds like to me that you are pretty settled on this girl. If you really think this girl is the one, then you need to do whatever is possible to overcome your fear. And its ok to be scared. Not every guy is macho when it comes down to relationships and its ok. Just stay true to yourself. I hope everything works out. Good luck :]
