He's Just a Househusband, Until the World Kneels

Xenia Klein spends three years married to a man she considers useless, and she has no idea why he married her. Elliot Judd was hurt in a cultivation accident and needs the energy of a woman with a Lunar Constitution to stay alive, and Xenia has that constitution. She will not sleep with him and keeps asking to be let out of the marriage. On the three hundredth time she asks, he signs. Elliot marries Sadie Wood, whom Xenia has idolised for years. He is not a man who goes back on a thing once he has decided it. Xenia is slow to take in that the divorce actually went through, and somewhere in there she works out that she has feelings for him.
