You cannot sustain attraction with your woman by doing the things she is naturally and traditionally expected to do effectively: changing diapers, cooking, and cleaning.
Doing all of this does not make you special. Because these are things she can do herself, your doing them will not register as some grand gesture deserving of special treatment. If she can do it, what, to her, is remarkable about your doing it?
People rarely attach exceptional value to services they can readily provide for themselves.
An electrician does not value the skills of a fellow electrician in the same way a doctor might. Familiarity reduces novelty, and novelty often influences appreciation.
Point is, attraction is utility-based. Shared capability rarely inspires the same admiration as complementary capability.
Changing diapers, cooking, and cleaning may not be the particular utilities that naturally command romantic attraction. They may make life easier, but ease and desire are not necessarily the same thing.
The ultimate and more intimate assistance you can offer your woman is to do for her what she cannot easily do for herself. What compels and sustains attraction, is a gap in capability rather than a shared capability.
Cooking, changing diapers, and cleaning may make you a better partner. But do not assume they will make her love or desire you more.
Those are different currencies, and they do not always buy the same things.
But i have said enough. Good luck. Or congratulations.
Modern marriages have turned Fathers to Second MOTHERS by asking them to clean and cook.
If she falls out of love, seeing you in the kitchen will start to disgust her.
