So i have a date on friday but im somewhat...?

socially awkward. It's horrible, I start this endless chattering and i constantly feel the need to fill the silence when it settles. What are some good dating tips for girls. I'm a girl and I'm going on a date with a guy. We already talked about basically everything the one night when i saw him at school. Also, i like him but i don't want to be forceful - should I let him know that i like him?? Or, should i let him guide?
