Hilchos Rechilus, chapter 7, section 5

5. The laws of believing rechilus are the same as those of lashon hara explained in part 1 chapter 8 paragraphs 13 and 14. Therefore, one must be careful to not accept rechilus from anyone, even from one’s wife. In the latter case, besides the sin of believing rechilus, when the wife sees that the husband accepts the rechilus pleasantly she will constantly tell him such things bringing him to anger, quarreling, and misery. Therefore, one should rebuke one’s wife if she relates such information.
