I pulled the pin 10 years ago. I was 42 at the time. It was with my highschool sweetheart. No kids. My home became my prison. I walked downstairs, made breakfast, took the house key off of my keychain and slid it across the table. I tapped out, said "you won, it's all yours".
Walked away with the clothes on my back. Slept in my shop for 3 months before I got my shit together and moved on with my life.
