Why would that be weird?? If he knows you like him, wouldn't he expect you'd want to keep in touch?
Text him and keep in touch. Ask him to meet you somewhere to hang out. If you don't you'll always wonder what could've, should've, or would've. Trust me on this. I know from experience.
He knows you like him alot, right? So, take a chance. You just might find out that he likes you too!! It's a text. How bad could it get? At least you'll know you tryed, but I have a feeling you'll be seeing him soon. Where's your confidence? Chin up and go get him. You know you want him.
Thank you! Look at it as a chance at happiness. Don't you think you deserve a chance to be happy? Every chance you have to be happy should be taken because in life, not everything turns out the way we want 100% of the time, especially if we let opportunities pass us by.
