She was a bitch.
She knew who she was now and she couldn't stand it.
She was a bitch for the simple fact that if it was the other way around; if Sean pushed her to have sex when she wasn't ready then he would unanimously be considered a jerk .
So why wasn't she?
Why wasn't she considered a bitch? Why did everyone tell her to seduce him because he must want (he's a guy they would say) it or he's gay or she's ugly or she's fat.
Or more importantly why did she listen?
He was a good boyfriend a good guy and maybe, yeah, they weren't meant to be together but the way she treated him made her sick.
She was a bitch to him to everyone so she shouldn't complain when bad things happen to her because she knows she deserves it.
But she'll be better she'll do better not for herself but for everyone else in her life because they deserved better.
Except for her dad, he can suck a dick.
