So she was worried someone gets hurt, but refuse to call a police?

Good luck with that. I tried. You may find that all those years you were "abuser" as well.

You assert that she should have called the police rather than simply leave. And then you claim that you were in the same situation, called the police, and found yourself accused of being an abuser.

If you had this experience, then you should understand why abuse victims often choose not to go to the police.
