Need help with this zodiac sign?

ive been dating an aquarius guy for about 2 months now and right now hes acting aloof and distant....i just want to know what do aquarius think about or daydream when they r alone??? also how long does it take for them to call back?? its been about a week and i havent heard from him since then..and im not going to call him bc ive called him first the last couple of times...
