Just remember that he is her father, and no matter what your relationship with your X, that it is a good thing that he wants to spend so much time for her. Children need both a mother and a father---many parents no longer care to have a relationship with their children at all once the divorce is final.
Take this time to learn more about you. Do something that you couldn't do with your daughter around--read some books, go running every day, eat vegetables that she doesn't like...watch different TV programs. You have been given a gift of time for introspection-use it--and when you do, let us know what you've done!!
