Tell me what you think of my plan to yell at my ex wife and accuse her of violating our parenting agreement.
This sounds like it might not end well. Why do you want to be so harsh with your ex wife?
She needs to learn a lesson the hard way.
You seem to be very angry when it comes to your ex, but harsh words and actions are just bullying her. Talk it out. You won't be as upset if you get some calm words in. You might even resolve things faster this way.
Don't you think yelling at her is enough?
Yelling at her will just make the situation worse. She will likely just end up angry at you and not want to cooperate. Instead, you both need to be mature adults about this and talk it out so you can do what's best for your children.
