DNiece and her DH have both been married before. Both marriages were long over before they got together. She has 2 DCs from her first marriage, he has 1 DD and they have a DS together.
The arrangement with the other parents has always been fairly flexible and aims to be 50/50, although now they are older friends and hobbies make it harder. DH had a catastrophic industrial accident while still married to his first DW. He received a large sum in compensation and when the marriage broke up gave his ex the house bought and paid for. She has always had a good job and as child care is shared he's never paid any maintenance but pays for school trips and other extras.
He is still unable to work and has had a series of operations and is likely to need more. He does some freelance IT work when he can. DNiece works full time and DH does the childcare of all their children when they are with them. Sorry it's long but don't want to drip feed.
Two weeks ago the ex had a huge row with her boss and walked out of work and has decided she doesn't want to work any more and DH will have to start paying her maintenance. His income is from investing the rest of his compensation after buying the ex's house and half of the one he lives in with DNiece. It is a very small income now but he will get a decent pension when the time comes. The ex says DNiece is earning so she'll have to pay. DNiece has told her there is no chance and to get another job. Ex is telling her DC they will be thrown out on the streets. DSD is very upset.
DNiece is standing firm but her DH is starting to waver because ex is threatening not to let DSD go to them unless they pay up. DNiece says they owe her nothing and she's certainly not having any money from her salary that she's earned. That's for her DCs and DSD when she's there.
I'm maybe too close but the ex is being U, isn't she?
