Who would he tell it to? Anyone you know? If yes, then it’s bothersome. Otherwise how would you even know what he says? Plus these women will find out the truth anyways. Didn’t he tell you he is a victim of abuse by his wife? But we know now it likely wasn’t the case. So he doesn’t get away with it.

Also people usually don’t care what their new partners say about their exes. Unless exes continue being part of ones life through involvement with stepchildren or through some other obligations (spousal support etc) or through continuous harassment of the ex etc, no one cares what kind of exes people had or what they say about their exes.

So he will be telling people he was married twice and both times women were crazy and abusive. Ok now. It doesn’t make him look particularly wise if that was the case.
