Turn it over to God and allow him to watch over your man. It's true, there's nothing you can say or do to change his course in life...only he can do that.
Time to focus on you and your daughter. Life is far too short to sit there and wait for any little tidbit he might toss your way. I know it hurts, but you've got to move forward and live your life to the fullest.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
