Ruling on fulfilling the wife's desire during the boycott in the bed

Question:
If a man intends to boycott his wife in the bed, but she solicits him for himself, despite the disagreement between them, should he refrain from fulfilling her desire?

Answer:
One should look at what is most beneficial. This is between the two spouses; one looks at what is most beneficial. If he sees that the most beneficial course is to agree with her, and perhaps this will remove the harm between them, he agrees with her and has intercourse with her. If he sees that the most beneficial course is to refrain, and that her harm is great, and that this will not solve the problem, there is no harm in his refraining from agreeing with her. The one present knows better than the one absent.
The point is: this is a matter between them. He knows his own benefit best. He looks at what is most beneficial.
