Then how does he repay her for her faithful service? By "capturing Krsna" and giving Him to her. Krsna is not so cheap that simply by baby-sitting, cooking, and cleaning the house for 30-40 years she can win Krsna. Every woman is doing that whether they are devotees or not. But a devotee woman literally buys Krsna by her chastity and "always pleasing" attitude toward her husband, even if he doesn't deserve it at tunes. Prabhupada says, "Chastity is the first religious principle for a woman." And Chanakya Pandit says, "A woman makes more spiritual advancement by washing the feet of her husband with water, than by performing sacrifices, going to holy places, observing fasts, etc."
It is very difficult to be chaste, humble, and always pleasing when the husband is not yet perfect, but that is the price she must pay for Krsna.
