Would a real, loving mother protect her child if her boyfriend tries hurting the kid?

I've heard of mother pushing their kid out of the way of an oncoming car while she gets injured or dies. Also those that saved their kid from a dog attack while she puts herself in harm's way.

But with a boyfriend or any other man in her life, she stands there, goes nothing and even when the man literally injured her kid badly or killed the kid (the worst thing a man can do to her), she's still covering up for that. One woman claimed to be to scared of doing anything. Even worse, she claimed that even if she would've saved her kid, the ex boyfriend would've killed her. Placing her own safety above her kid's life!!!

Honestly wouldn't a real, loving mother protect her child against anything or anymore, even an abusive partner?
