I don't even know this guy's name? Help!?

Well I went to Tennessee for my cousin's graduation and I live in Louisiana. Well we stayed at a hotel call 'Emby Suites' and it was very nice. Well we just got home from dinner with my cousin and the rest of the family and it was the night before his graduation. My family and I decided we would go swimming. Well when we got down to the pool area there were guys. Of course I just stayed in the hot tub. Well this one guy came over and got in. I found him attractive, as I do a lot of guys, but there was some different about him that made my stomach just jump into my throat. I of course got out after he left. And we headed back to our suite. This particular hotel was kind of square shaped and the rooms were on the sides so you could look over the railing outside your room and see what was going on in the lobby. Tired of my family's racket I stepped outside and looked over the railing (as there was a wedding dinner rehearsal that night) and just sitting there when I noticed the SAME guy from the hot tub walked out and was looking over the railing two floors down from me. I watched him from the corner of my and saw he periodically looked up at me. (I pretended I didn't notice) Finally he asked me if I was "Just chilling" and my whole stomach jumped. I was like "Yeah nothing better to do round here..." After that my mom came out and told me to come inside. The next morning I got up got dressed and headed down to the gift shop and I noticed he was down in the lobby too. I played it cool and pretended not to notice him. I walked in and saw him walk into the gift shop as well. I started looking around and realized I couldn't even afford a coffee mug! So I left and as I did I noticed he walked out to. As I walked into the elevator and punched the on he walked in... And he got on his floor and I went back to my room. Couple hours later I was getting ready for the graduation. My family was already downstairs waiting for me. And I had my cutest dress on. He watched me walk to the elevator and watched me as the elevator went down (they were gl so you could see who was in them) not trying to hide that he was clearly staring at me. I was soooo flattered. Then about 5 hours later we came back and as we walked to the front door I noticed he, his dad, and his friends were sitting on the couches next to the door. Well as I walked in he immediately stood up. I know WTF? Anyways, I realized I had major feelings for this guy yet I don't know his name. I knew the next morning we were leaving and I was really upset. Well morning came and we were carrying our bags out and I saw his family and his friend's family with their stuff piled up too. We kind of exchanged sad glances. And as we got down to the lobby (him, his family, his friend, and his friend's family were still on their floor) he was watching me and his friend was rubbing his back as if he was comforting him. I almost bursted into tears right there. Well as we started our nine hour journey home (which was today) I thought of him the WHOLE way. As soon as I got into my room I started bawling! Then I picked at myself saying that I'm pathetic crying over a guy that I'm basically strangers to and will most likely NEVER see again. I'm crying my eyes out right now because I know I'll never see him again. I have never known this feeling of my heart aching for him ad my stomach queasy all the time. Especially towards a guy whose name I don't even know! And I know you are probably thinking I'm just a lovesick teen but that isn't it. I've never felt this way, and I've never wanted someone so bad in my life. What is the feeling?!
