He was the only one who could change the system.

By Monday Morning Every Automatic Payment Was Canceled and Every Decision He Made That Weekend Was Precise and Deliberate
He started on Saturday night and finished on Sunday.
The automatic payment covering Beverly’s car insurance — canceled. The credit card linked to her accounts — removed. Every subscription, every automatic transfer, every recurring arrangement that had been running in the background of his financial life on her behalf, one by one, resolved.
He contacted his broker on Sunday evening and instructed them to list the property Beverly was living in. The house he had paid off, kept in his own name for reasons that were now clearly relevant. It would go on the market. Beverly would receive proper notice, as any tenant would. Everything would be handled correctly and legally.
Then he turned to Sydney.
The housing fund he had established for the subsidized rental she and Grant occupied — ended. The arrangement he had put in place that allowed them to live in a home at a rate that bore no relationship to actual market cost — over. Sydney would receive notice that the rental was being taken to market rate, or that he would be selling, and she would have the time a tenant was legally entitled to in order to make alternative arrangements.
He did not do any of this angrily.
Anger would have made the decisions feel temporary — contingent on the emotion, subject to revision when the emotion passed. These were not angry decisions. They were the decisions of a man who had looked at a system he had built over ten years, understood what it had produced, and made a clear-eyed judgment about whether to continue funding the outcomes.
The answer was no.
He was not punishing them, though he understood they would experience it that way, and he understood that their interpretation of events would involve him as the aggressor in a drama of their own construction. They would say he had overreacted. They would say the dinner was not that bad. They would say Macy had caused problems and he had let her manipulate him.
These interpretations were not his responsibility to manage.
What he was doing was not punishment. It was the withdrawal of subsidy from a system that had produced people who told his pregnant wife to eat in a bathroom.
There is a difference between generosity and enabling. He had spent a decade conflating them, and the dinner in Asheville had made the distinction impossible to ignore any longer.
