She said some genuinely terrible and severely cruel things to MC and then the author played it off like they were both just as in the wrong...no screw that.
She was told she was embarrassing and should conform to how her sister dates/goes about relationships while also bringing up the man who hurt her in the first place? Fuck off with that bullshit, this is judgey behaviour DESIGNED to hurt someone that family gets away with but it's not healthy behaviour to allow someone to talk to you like this.
First and foremost you don't just get over a whole heap of self esteem issues and relationship issues through sheer force of will, then you have asshole family picking at the scab and purposely bringing up the person who traumatised you as if severe shock, pain and realisation of long it's been will make you suddenly want to date again? I for sure wouldn't be talking to someone for quite a while if they spoke to me like this.
Ugh. I hate it so much.
