My ex has had some of the most unsuitable, disgusting things come out of his mouth. Pointing it out has not made things improve. Usually it has made him more angry and accusatory of me. He will not likely be receptive to anything you have to say.
It is far better for the kids to speak to it if it bothers them - not you.
I had to learn this the hard way. My MLC ex does not want the Mommy figure admonishing him.
