1) Behaving in a way that your daughter wants to spend time with you.
2) Fighting for your parenting rights.
You do number 1 in every interaction with your daughter. You do number 2 through emails with the mother (using lawyers, judges and other professionals as needed.)
Keep working on you. There is always room for more positive personal growth.
How many parenting books have you read since the BD? Are you a better parent now?
