It is very easy to say that. I'll admit I even said that when watching stuff about domestic physical abuse. Why don't they just leave? How hard is it to walk out?
If only. It's not as cut and dry as we would like it to be.
Imagine, you are 24 years old. Remember being 24? You aren't as nuanced about the world. And you went through a lot of personal trauma, but finally thought you found a silver lining with a new dream job. And being 24 and naive you don't see the mind games your new boss is inflicting. You are being manipulated and gaslighted and you can't make heads or tails of it. You are told you are the problem. Remember, you're 24 -- not 34, 44, or 54. You are still impressionable and you begin to believe it is really you.
Finally, something clicks years later, your brain is getting out of the fog and you realize you need to get out ... and NOW. You lose everything and have to sell your personal possessions to make ends meet. And you do. And you survive. And you live to tell your story.
Geez, give the man credit for self preservation! A lot of people being abused never get out because they can't envision a way out, they are stuck in that fog.
