i had one foot out the door, emotionally, mentally i was already gone, i just needed something to finally pull the trigger.
We'd been together 16 years, i'd left once before 7 years prior and come back, told him if he pushed me to that point again, that would be IT.
We'd had a few months of the relationship completely dying, i didn't want him to touch me, he knew it, was ramping up the abuse, started to get more and more controlling and nasty.
We got into an argument over something i wanted to go to, that he didn't want me to, he started laying into me about my friends about how he hated them, accused me of sleeping with them (i wasn't) and i just.. snapped. Told him we were done.
I left the next day. never looked back. Best decision made in the heat of the moment ever.
