If so, everybody knows it, should I care or not?

If I donot tell, it helps the guy the most, in some sense it also helps me a little bit. Since we are done already, why have to let everybody know? On the other hand, if they go on pushing me, I have no other option but tell. And after all these, the hus. and the wife will live together forever, although for the time being the guy is kicked out of his house by his wife in order to threaten him.

Either, I do nothing, just wait until sth or nothing happens.
