He sounds aloof. If a man is interested, he Will contact you and make an effort. You've let him know you are interested, so I would back off completely from initiating contact. Personally, I like when the guy takes the lead. Then you know he Is interested and you don't put yourself though all the questions and doubts. Good luck. I've been there so I know how it feels when you like someone and you feel like you're not getting the answers but sometimes they're giving you an answer by Not saying a word.
