Well, now you know why you were being nagged to replace the damn thing.
You really are in the shit now, this is a big YDI.

It's your shit, you clean it up

The seat took a hitting while you were still shitting.

You need to dump your fiancée, fix the toilet seat, and find someone new.

If you marry the current one, every nag for the rest of your life will involve you breaking the toilet seat and shitting on the floor. A man can’t live that way!!!’

Seems like an over-reaction to me, it's only a broken toilet seat.

I'm curious, since your fiance sounds more like a woman (based on the nagging), did you misspell the word fianceé or are you in a homosexual relationship? :)

Don’t be a tool, dude.

should have fixed it when he ask you too and now you're in a shitty situation

Oh, no, you ditn’t!

I'm thinking this was a inside job. What meal caused this emergency visit?

So the question is, is the shit bowl half filled or half emptied?

There's a reason why we "nag" you to fix shit, and that's why. Maybe next time you'll fix it the first time your fiance asks you to.

Given your fiancé has to sit everytime she uses it, you're truly an asshole cus that's what she was risking everytime.
