I'm sorry

You mentioned domestic violence. I'm a dv survivor. They promise to change (abuser)...they don't. It's a vicious cycle. I left three times and the only reason I returned because I knew if I ran that instant I would be beat or killed. My final exit was planned carefully.
It isn't your fault and your not to blame. Can you visit a friend or family and use their phone to call a shelter? Pack essentials, i.d etc? Believe me once you are out...freedom is wonderful. I required several surgeries due to his physical abuse. No one can force you to leave. Just know that you deserve to feel safe and free from abuse.
