Tools for leaving your abuser
You’re getting there. You've started to see that Jerkface isn’t a normal person with a normal heart. It feels like their relationship with you is a game, a lie, a selfish arrangement. You wonder if they’ve lied to you just to keep you trapped in their web. And you may finally have had enough.
Therapy with Jerkface will most likely be unhelpful, and at worst it could be very hurtful - to you alone. Therapy must be based on trust and goodwill - neither of which a Jerkface is able to bring to the table.
When a Jerkface has lost control of you (e.g., when you leave), s/he is all about getting that control back. That means Jerkfaces will say or do pretty much anything to get you back in their clutches - including pretending to understand your pain, promising never to hurt you again, even volunteering to go to therapy.
