You can tell her due to the pressure, she doesn't need to b forced to call you either. That isn't what makes her a good parent. Respecting her daughters wishes will make her a good parent. Being a parent is not forcing your 7 year old child to take part in scheduled phone calls. That call has nothing to do with the welfare of the child, it has to do with the parents wants.

East, I know you are stuck in a really crappy spot. But please hear me.

It would be advisable to get your little girl into IC ASAP. This is not good for her. Then you will have documentation of what your ex is doing also. Then you need to get that lawyer. You need to get a more reasonable parenting schedule in place, because what you have is NOT working. The freedom to see her if she chooses during the week can only be done where there is no hostile relationship between the parents. Once you set this schedule, you communicate via a shared calendar and emergencies via phone call and texts. You both have access to the school to know what is going on with your child. YOu end these scheduled phone calls on both sides and remain open for when she chooses to call the other parent. You turn off your phone when she begins text ranting and calling non-stop.

This will NOT make you look bad in the eyes of the court at all if you properly document and get help for your girl. The truth will come out in IC. She will have a neutral professional party where she doesn't have to worry about what the other is saying.

Please, please, please, be proactive. You are the stable parent, but it's not going to be enough at this age and with what's going on, and that is no fault of your own.
