Case. One partner earns noticeably more and starts making decisions alone; the other feels “junior”.
Model. The right to a voice got tied to income — a role-model (IAM) error: privileges should match the partner’s role, not the size of their financial contribution.
What helped. They separated “who brings the money” from “who has a voice”: decisions are joint regardless of income.
Lesson. A marriage is not a corporation; a voice isn’t bought.
