It seems like although you fell in love at first sight, he wasn't impressed if a week has passed and he didn't call. It's not worth it to turn to astrology for someone you don't even know. If you want, call him and see if he wants to go somewhere with you. But don't gauge his interest or lack of it by astrology. It only works for serious relationships. What you are asking is really more in line with a tarot reading. But since you liked him I hope you call goes well!
