I watch a lot of true crime, and VERY often, the wife/mother will sacrifice her kids’ safety — even lives sometimes — to appease her man. The abuse can be stunning and often the mother is aware of it. The children aren’t the priority.

Selection Effect.

The countless instances of women giving preferential treatment to their children, to the detriment of the new boyfriend, don't get made into "true crime" shows, because it's the norm, and thus boring.

You realize that mothers give preferential treatment to their children even when married to the biological father don’t you?

The difference is the married bio dad recognizes the need and fitness for it and isn’t stupidly seeing his offspring as competition.
