Does he like me?

Ok so I am 14 and I am a freshman in high school. I just visited Washington D.C with some of my friends and the guy that I liked went too. We had to take a plane there and back(it will make sense later). Well while we were there he would flirt with me a lot when we were alone and we toured a bunch of museums and stuff alone just the two of us,we were laughing so much and having fun, but as soon as we got back together with our friends or just the group he was either super rude to me or wouldn’t talk to me. Also we were going to the airport and he sat beside me on the bus and our touring group got food at the airport, he invited me to share a pizza with him so we did. Then we got our tickets from our tour guide and we had seats next to each other on the plane. The plane ride was amazing he was flirting with me non-stop but then when we landed he was rude to me again because my best friend was around. He is really nice to me and he makes me smile, and we both love being around each other. I think he likes me but wants to act tough around his friends. What do you guys think? Comment below...
