Women who end up married to selfish pricks, don't suddenly arrive there.
Invariably it is a boiled frog situation as in this case.
OP has been tolerating and "managing" a selfish sulky man whom she now knows is a liar.
He's not a good man.
He now is doubling down and ppaying chicken with her, as to whom will crack first.
He's a shit husband and father, and a liar to boot.
His sulkying silence is also abusive but OP has been trained by him to manage this.
OP doesn't mention work, housing and finances, but when she has time and space, she should think about her future and what she wants.
She definitely hasn't married a good man and long term she may want to change her status, on HER terms and time line.
Going forward she can drop the rope, stop making his life comfortable, do nothing that benefits him, detach emotionally, confide in friends and family, and plan, plan, plan.
