My ex and his girlfriend have both been abusive to me. I left my ex due to his abuse. We have a 5 year old son together.
His girlfriend will have a baby soon. The ex constantly badgers me about the baby and how I should be grateful that he is giving our son a sibling. I try to ignore it.
I am my son's primary carer and I schedule important things and social events when my son is scheduled to be with his dad.
My ex and his girlfriend both have family in the area.
Ex demanded that I be on call to go pick up my son, including turning my phone on at night, if the girlfriend goes into labour. I told him he needs to sort himself out, though I did agree to cover some of the times when I am not working or sleeping.
He is now rumourmongering about me at school.
AIBU to tell him that he needs to find childcare if his gf goes into labour during one of the (infrequent) times he is responsible for our son?
