Not mine but my DM's final straw with my not so DF when I was 18 months old.
He came to the flat steaming drunk and 3am and proceeded to start pounding on the door & screaming all over the block that my mother was drugging me and abusing me because every time he 'visited' I was asleep.
DM tried to calm him down but obviously there's no reasoning with an alcoholic on a rant, he pushed her called her a whore and slapped her, she was so scared that he was going to get in to my bedroom that she said something snapped in her head & she grabbed him by the shoulders, kneed him in the stomach and threw him out for the last time.
He stayed outside for a while shouting until my uncle came and removed him from the building.
The way she told me when I was 12 and now over 15 years later is exactly the same it's like it's burned in her memory. I never saw him again either, he died when I was 16 of liver failure due to alcoholism.
It breaks my heart she went through that, she was and still is the best single mother in the world she's a tower of strength and I love her so much, OP and every other woman on this post sending you love
