But the job he does, where we live, the house we live in, even the job I do are all the things he has wanted and I have gone along with but none of it seems to make him that happy (or only rarely).
He's gone all week, which she doesn't want. And when he's gone, who is looking after the kids as a lone parent, while also working? Who is doing ALL the care of the kids and their home? Her flexible work is making his work - and his jettisoning all the many boring, grinding, daily tasks of parenthood - possible.
When he's home he's unpleasant and makes the whole house tense and miserable, but again, you think this is fine because it revolves around him entirely. She has sex with him every weekend despite not actually wanting to, because he's unpleasant to her. That's vile.
After all this, she says: I should say he’s a brilliant family man. He absolutely puts us first at all times.
I can't see evidence of him putting them first at any time, ever.
What part of this life is not run around this man's wants? A woman is not his emotional support animal, her life revolving entirely around his choices, wants and needs. She's a human being, too. This is her own one precious life, too.
She says she dreads him coming home. That's not a partnership, and it's certainly not a marriage. That's an oppressive, soul-sucking chore.
It is the apogee of narcissistic entitlement to believe other people owe you their company, if you can't be arsed to be anything but unpleasant. If that's what someone wants then they need to resort to AI to get their needs met, and not flesh and blood human beings.
