Hello and Thank You for using Just Answer. I am sorry to hear about the problems that you are having with your ex. Your situation happens quite frequently when one parent bad mouths the other in a divorced situation. As long as you continue to be the loving, supporting, and encouraging father, your daughter WILL begin to see that her mother is trying to make you out to be a bad person but your actions will speak volumes. Do not worry. Your daughter is old enough and will see the games that her mother is trying to play.
