A lot of people walk away from physically, mentally, or emotionally abusive relationships. I know many.

Reading the question generously, the person is asking why someone stays instead of leaves. Two of your 3 examples are emotional manipulation (big red flag, run away) and the last one is a threat to your life (big, big red flag, run away).

I think it is reasonable for someone to not understand why a person would choose to stay in that situation.

Of course, life is more nuanced than that, and the rash of pro athletes lately that have been exonerated from these accusations further muddies the waters.
