But wait, it wasn't exactly out of the blue.
She went on to explain that the toilet in her apartment broke and her boyfriend insisted he'd fix it.
He did fix the toilet but never let her forget about it.
"He's thrown it in my face ever since," she said. "Every little dispute we had it was, 'You're gonna be like that after I put so much money in this apartment?'"
The broken toilet incident happened a few months ago but it seems he was not quite over it.
According to the now ex-girlfriend, the first words he said after she announced she wanted to break up with him were: "I'm taking the f*****g toilet!"
"He's a licensed plumber so he knew what he was doing," she said. "Every breakup just gets more and more interesting."
The Redditor says this is "the most insane breakup" she's ever been through.
