Can you tell me what he wants?

Hey guess what- I read the whole thing! Haha, I feel proud. But about your question- are you asking if he's into you? Because if that's your question then the answer is yes! It's extremely obvious that he likes you and wants you. I don't really think there's a need for me to explain, it's all in your question. However, I'd be careful with an older guy... wouldn't you rather be with someone your age? It just seems a bit odd to me to go out with a man of that age. If he's checking you out and flirting with you at his age, and then says he acts like he's 17, this makes me think he's pretty immature. If you don't have any contact with him now, I'd keep it that way.
