Not gold diggers, but quite happy for their wives to be complete work horses.
In a vaguely similar situation, my nursing friend had the same pressure from her lazy selfish husband.
She duly spoke to HR and increased her hours, but starting at 7.30am.
This change mean HE would be getting two children out the door in the morning, a job he had scrupulously avoided to date.
He wanted different hours but she refused.
He was cranky doing it and when her son complained that Daddy was very grumpy in the morning it was the catalyst to talk to her parents who lived nearby.
They offered to step in and drop the children and on that basis she told him she wanted a divorce.
She wasn't happy, and the final straw was realising her children were being impacted.
It was a complete shock to him that she was done.
He clearly didn't want the marriage to end, so told her things would change, and they did.
The changed only cemented in her mind what a fool she had been tolerating his laziness.
Good men don't use their wives as workhorses, arseholes do.
