What's the harshest way you've ever broken up with someone?

I launched a girl out of the earth's atmosphere when she told me she needed some space.

Girlfriend became angry over something meaningless and stormed out of my place at 2Am... didn't hear from her in two months.... she showed up late one night at my work late at night to give me a ride home.... once back at my place she took a shower and shaved her legs and put on lingerie... then she came to bed and said she was tired and just wanted to sleep... I told her my house isn't a hotel.... I was angry that she'd tease me... I had no idea what she'd done the past two months but denying me sex after following me home late at night and feigning an encounter would occur by preping and then coming to bed like that was too much... she was yelling at me but I remained calm as I gathered what items she had left in my place throwing them
In a box.... I threw the box outside my place... the contents exploded in the courtyard... I told her to get out..she left crying and didn't return... she still texts me 4 months later... wants to meet up... I'm just so done with her.

I told him I didn't love him. That wasn't true, I was scared and didn't want him to know I had been molested.
I really hurt him.

I walked into a party at his house and called him a jackass. I told him I never wanted to see him again and to delete my number. And I said he was just as pathetic as everyone assumes he is. In front of everyone. And then I walked out. He followed me out of the house and I just got in my car and drove off and smiled and waved to everyone.

He was a personal trainer...he was always talking about how people automatically judged him as a "player"...

Broke up with one guy the same day he had told his grandma that yeah, I was his girlfriend.

Followed them into the ladies toilet when they wouldn't stop running away.

I broke up with my ex over text, telling him that I wasn't ever really sexually attracted to him and that's why we never worked out. It really hurt him.

tried to balance 2 girls friends , it was a disaster

I got ghosted once. Didn't appreciate it tbh 😒

It wasn't harsh it was just necessary.

I rarely break up. I'm clingy

I haven't
