You are doing what is best for you.
You are protecting yourself from his drama/abuse that he may hurl at you later.
If you called him and accepted his offer to sit with the sick child after his last tirade, your actions would be telling him it is okay to treat the mother of his child with disrespect.
It is not okay to be treated with disrespect. You are doing great!
