Does anyone else feel this way?

OMG this is exactly what I am going through! I went to DC the other day also and I sat by this guy who flirts with a lot of girls and he flirted a lot with me and I loved every minute of it. We fell asleep together, we held hands, we rubbed my back and played with my hair. I wished it would last forever! But now that the trip is over I don't think anything will come of it. I just don't know if it was a fling or if he actually likes me, because he is so flirty with everyone.
