Yes, she was very quick to accuse him of violence and abuse so she showed zero boundaries, privacy or respect in my mind.
I've always felt like it was more he who may have done the dumping, I'm purely speculating though.
- He may have looked sad but could it have been sad because it's over? Maybe her turning to smile at him was her trying to force herself to be okay
- The way she was over Oliver especially the way she very rude to Pete in that video. Is it possible the crush and the patronising drove him away?
- accusing him of abuse but being vague and sketchy. She did say that it was mainly property damage - could be more too that though?
- He deleted all trace of her on his social media very quickly, unlike her who has kept on of his presence on her Instagram (still, as far as I know) and has only recently hidden videos featuring him
- Seemingly jumping into bed, literally, with Oliver very, very quickly. The saying goes to get over someone, you get under someone
- The old Tumblr post she put up seemed very brash and she claimed at the time, they were too different to be together and then stated they'd remain friends but didn't at all
There's a few more I can think of but I'll post them when I remember.
I'm just speculating of course but I don't know, some things lead me to suspect that maybe she didn't dump him, it could have been him.
Just my two cents though, of course
