My friend is married to a guy like this. They have 2 kids and have been together since we were teenagers.
Since having kids she is a freelance creative making not very much around her childcare duties (95% including all night waking, feeds, nappies, house work). She pays for half bills, all childcare, kids clothes, toys, things for the house, plus her own needs (like her battered old VW Polo). She often can't come away or go out with us as she has no money.
He, meanwhile, has a high paid, skilled job, lots of OT, and does about 2 half days childcare pm, pays half bills and all mortgage (which is solely in his name). He often goes away on snowboarding trips with his mates (while she looks after the kids, obvs), drives a new VW, new trainers all the time etc.
There's nothing wrong with having no money, but you should be in it together. Instead, he lives high on the hog, and she scrimps. I've tried, very gently, to get her to see how the financial cost of doing all childcare and housework isn't being recognised, but she's in too deep now, and doesn't want to face it. Plus, they're very happy so long as she doesn't rock the boat.
Does that sound like the kind of life you want for yourself?
