If you like a guy and he likes you back but you don't talk to him much and it's awkward to talk?

most likely you both like each other. Try just talking about normal things, or get close to his friends mainly the one's with big mouths. Lastly be brave and ask him out. If he turns you down, just keep your head held high since they're a lot of fish in the sea. Don't say "Would you like to go on a date?" instead, to make it less nervous for you and him, say this, "I'm going (name of activity or place) and I was wondering if you would like to come along to have fun?"
