As a guy, my best theory is that he is weighing his options right now. You'll hear from him when he has made his decision.

I'm a firm believer in "once an ex, always an ex." There was a problem the first time around that caused the relationship to fail, and its bound to happen again.

I'm a needy guy. The lack of time together and lack of sex would be turnoffs for me, but each guy has different preferences.

Best wishes and good luck.
