This is worth re reading.
You are doing so well, but his relentless poor me is just further truth that it is ALL about him.
NOT the children and doing right by them, but focusing on him and how this inconveniences HIM.
You are such a nice woman, but at some point I hope you will get to realise that he is showing you NOW exactly how his mind really works, and just how much you were targeted for your home and set up all those years ago.
There really no man as loving as one that needs a home, even more so with 3 wild children in tow.
I have no doubt with your previous examples of how petty and PA with you he was, that he is absolutely furious at you for doing this.
This is a huge inconvenience for him and not one that will not take a substantial amount of time to fix.
He will try. He wants to game, not rear children and skivvy for them.
I honestly do expect a crisis to erupt.
Job, health, self harm, the children.
All to try and to drag you back into his mess and trigger your saviour gene.
Men like him aren't that bright.
He will be desperately grappling with how to reverse this, no matter how ridiculous, dramatic and convoluted it looks.
Desperation does that.
Do not allow him enter your house if he turns up in drama mode with or without the children.
This week will be an increasing shit show to him of the reality of whats involved in parenting without you.
He will become increasingly agitated as he tries to fix this.
Protect yourself, your son and your home, and don't hesitate to contact the police to do a "welfare check" should he make even the hint of a self harming.
Hand it 100% over to the authorities.
Sorry this is long. You are doing great.
