Hi how are you doing.
Well this sounds very sad. All i can figure out in your write is, your ex is been very selfish, and this is NOT good for both of you and thile kids.
I will advice you schedule a time, reach out to me on here so lets talk okay. Been in same situation before, but i was talked out of it.
Lets have a chat around this and see how it goes.
Take care and be strong….
