Do you ...

...feel unsure of where you stand in your relationship?

Do you have obvious physical or emotional signs that act as
    red flags to run, but you stay?

Do you wonder why the attachment is so strong but you
    are unable to leave?

Do you keep hoping things will get better when they don't?

If you identify with any of these questions, know you are not the first person to have felt this way. Thousands of people experience dangerous pathological men. They don't change.
They are entirely about dominance and control.

The answer to your suffering is not to help them change, but to get out and learn to have healthy, satisfying relationships in the future.
