Was he interested OR not interested OR did my ignorance put him off? HELP!!!! :(?

Well being 16 and infatuated is hard to deal with. Your post isn't long, I've seen much longer. Everything that you have been doing is well "playing hard to get." It's normal, the only problem is that he hasn't caught on. Maybe he's just not that smart. You like him, he just doesn't know it. Let him know. The thing is with relationships at that age is that one of you will most likely move on to someone else. If you two really like each other things will work out once you make it clear you like him. Hopefully he's just a little air headed and hasn't caught on to your hints. So just make it obvious.
