SA, I'm so very sorry that he didn't go with your daughter. Memories such as these are priceless and can never be duplicated.
I agree with Bea, you are a wonderful example for your daughter and she knows that you are there for her every step of the way. Never doubt yourself. Cherish the memories that you are making with her and remember...she's cherishing them too.
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.
