It is fabulous that you are getting response from H when you initiate. It works, so allow yourself to continue (when YOU want it) unless it stops working. (I would love to NOT be rejected...I have given up all initiating in my situation.)
What plans do you have to db while you are away? The time separated will be a great time to practice putting up the stop sign...release yourself from the crazymaker monster! You may need to make a plan for yourself to figure out how you want to prepare.
As far as H not initiating, become curious. Maybe think back to the times in your life when he had been initiating. How did he initate? Where and under what circumstances? What were the signals? Could you be missing some of these now? Or as Underdog said, maybe he IS fearful of rejection...
