Ok so here i am gonna explain todays events and will someone help me figure myself out?

Today at 5:30pm, i went into town with my bros and mate Jake to go to a Yu-Gi-Oh card Tornament thats on every monday in my town. I Went and began trading my cards with other people there. Now me and my other friend Kiwi [Kayleigh] had gone before and spotted this TOTALLY yummy guy but we didnt know his name.

Well tonight she wasnt there with me but this guy was there again today [we have gone the past few weeks but he never turned up its the first time in weeks since i last saw him] Well yeah he was there again today. I smiled at him and he smiled back, I asked him for his name because i had forgotten it and his name was Luke. He's 17 years old.

now apart from that i ignored him until the duels started and break came. i chatted to him and another guy Liam. Once during the chat, he rested his head on my shoulder, i didnt take it as anything. I said i had a fettish for touching guys hair (weird, random and amazing but its a true fact) Luke stood up and went to pull his pants and i laughed and said "No! hair on their head!" LMAO he laughed and sat back down. The next duels started and he said "We're both sitting here because i want to talk and chat to Abi" He said. I smiled and found out we were duelling each other.
He beat me, but then after he came and sat back next to me.

Strangely enough Luke had a card i wanted, but his one wasnt up for trade. But my brother wanted Luke's Blue eyes White Dragon in ultra rare, Luke said "I'll swap my blue eyes for hamon" And so he traded it with my brother.

Well As i was duelling he passed me a card. I told him to wait until i was finished, so i could give him my folder to trade with the card. "No, you can have it," He said, passing me the card. I smiled at him and he smiled back.
Now i was loosing my duel with Jake. "Great, i'm screwed," I said. He leaned over and said "let me check" and he tried to help me. Unfortunatly i still lost... :/

Luke turned to me and said "Hey you live near me right?" He asked. I smiled knowing i saw him outside my house before. "Yeah, i do," i replied. He smiled again. "Do you want a lift home? I have my car outside," He asked. "Um, sorry i have my brothers with me," I replied. "How many is there?" He asked. "Just 3 me and my 2 brothers," i replied. "I'll give them a lift too, its good," he replied.

So we caught a lift home with him, me in front next to him. I learned more about him when driving home. I already knew he was 17, he enjoys Yu-Gi-Oh and loads of other stuff. OMG i liked him so much, and i said that my friend Kiwi and i wanted his number, he gave it to me.

He dropped us off and i text him. The only REAL problem is that he has a girlfriend. but according to him girls dont like him for long...

I text him saying i liked him but he hasnt text back yet and this has REALLY confused me and smashed my confidence to peices.

SO. HERES MY QUESTION TO YOU GUYS. PLEASE HELP ME! >.<

He gave me a card worth quite much for Nothing. He rested his head on my shoulder. He made me laugh and joked with me about pulling his pants down. He gave me his number. He drove me home.

Is he interested in me? And if so or not, is he worth pursuing and if so why hasnt he text back?
