Is my best guy friend falling in love with me?

My best guy friend Jay and I have known each other for the past 2 years. Last year, I started dating my now ex boyfriend Kyle, who is best friends with Jay. When I had been dating Kyle for about 8 monthes in, I started talking on the phone with Jay almost everday and hanging out with him more and more I even slow danced with him at a bar mitzpha (Kyle wasn't there). Just after my 1 year Anniversary, our other friend Adam thought that Jay was trying to steal me away from Kyle. A few weeks later, Kyle broke up with me. After that, Jay and I became even closer and now we do almost everything together. All our teachers think we're dating. He always plays with my hands and we flirt all the time, but he has a lot of other friends who are girls, too. Besdies that, he tried to "set me up" with this super annoying guy for my "rebound." He also semmed upset that Kyle dumped me a few weeks ago. I know this seems sorta stupid, but does he like me? We're 14 btw! Thanks! :)
