When a man stays with an abusive woman
I credit the Knight in Shining Armor Syndrome.
Some men are attracted to a woman with problems
in the belief they can change or save them.
Not sure what the female version would be called.
I believe it’s the idea that if you rescue a man from poverty or whatever, if you mold him he’ll turn into the decent man who will become a success.
Like Britney with K-Fed. She married him and he was supposed to become this perfect husband and when he didn’t, Britney dropped him and flaked out after realizing the loser she had taken up with and actually had children with.
