Phone calls are only for emergencies. No more acknowledging drivel. You only respond to things that you need to respond to. Her mould (American's spell it wrong!), her house, her problem.
Cute stories about the kids? Enjoy them but don't respond or acknowledge.
She gets irked when you don't respond. Don't respond or acknowledge.
She goes off the deep end and starts hurling abuse. Don't respond or acknowledge.
She confronts you about it - you say you will only respond to issues that require response.
She is only to call AT ALL in case of emergency. All other comms via email/text.
If she breaks this you put your request in writing each time. She will get the picture eventually.
Crickets all the way. Surely you can see she is grasping at straws here?
I have had to ask the sad clown to stop with the unsolicited contact. Kid/finance related but a total stretch. None of it required my attention.
She is fishing brother.
I suggest you start using my mantra is:
There are no fish in this pond. This pond has no water. Fuck Off.
