Never speak of marriage as an achievement. Find ways to make clear to her that marriage is not an achievement, nor is it what she should aspire to. A marriage can be happy or unhappy, but it is not an achievement. We condition girls to aspire to marriage and we do not condition boys to aspire to marriage, and so there is already a terrible imbalance at the start. The girls will grow up to be women preoccupied with marriage. The boys will grow up to be men who are not preoccupied with marriage. The women marry those men. The relationship is automatically uneven because the institution matters more to one than the other.
