Hilchos Rechilus, chapter 7, section 5

The ban on accepting rechilus is the same as the ban on accepting lashon hara. So he must be careful not to accept rechilus from anyone — even from his wife.

When he listens to rechilus from his wife, besides the sin itself, he brings a lot of trouble on himself. When she sees that her husband listens to rechilus, she will keep telling him such stories, which will upset him. So a person who cares about his soul should say something to his wife in such a case.
