What does he think now?

he might have gotten the wrong idea when you were hanging out or talkin on fb and trust me guys often mistake girls being friendly and take it as flirting so im not sure exactly what he thinks but he mite be wondering if you were trying to hit on him and thinking about how he should handle it cuz (im guessing) your younger than him so give it a little time and see what happens or if you want just ask him straight up if he thinks you were flirting and tell him u didnt mean it...hope i helped
