Trusting, It's more than your being successful with the business. He's worried that you will not be right where he left you. He sees that you are moving on and he's not a part of the mix, so to speak. He's afraid that "mom" is becoming very independent and the aprong string is growing smaller and smaller and soon...poof! It will have slipped through is fingers.
Continue being the person you've always been. If he contacts you again, listen, but do not offer advice.
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.
