My ex hubby has requested for more days with our daughter. She goes stays over with him one night a week. I am not comfortable with that. Can I say no? What happens if he insists?

May I know if there is child abuse? If there is, please report to the police. In a divorce situation, it is best that a parent can spend at least 1/3 to 50% of the time with the child. That means at least 2 consecutive overnight. Listen to these children! https://www.youtube.com/watch?v=Edb9plpHO7k The choice is with your daughter, you should ask her opinion. If you insist is your choice no one can stop you.
