Shooting him straight in your own words is a great idea. Please be mindful of his feelings too as the idea that dating you "might be a possibility" could make the romantic in him "wait for you" and then miss out on dates with other girls who might be an even greater match for him.

It's not so much a problem but he sounds pretty innocent seeing as he's been alone with you several times trying to work up the courage to make a move. Try not to string him along.

Thanks for sharing.
