friends

I have a friend w benefits. He's 19 & let's just say I'm a little younger & we met up once after meeting on Instagram but we used to see each other at school ) the first time we met up to hang out we kissed, 2nd time we did it.. last week. He had a girl when we first kissed but he didn't say shit because I told him I liked him & he didn't tell me he was with someone.. so they left eachother a few weeks ago. Then we did it in the car .. I was so claustrophobic but it was a good night. We still talk and he still gave indications of seeing me soon like going to the movies, or taking me to work, but the funny thing is, when I try to flirt, he seems to be dead asf about it like if we never did anything. I'm over thinking stuff like if the sex was lame or what could be wrong w me:/
