What exactly happened?

Hmmm She didn't break up, as I heard, she said she doesn't want people to talk about that part of Felicitydraws and wolfyart123's relationship. According to wolfyart123, you 'Made her uncomfortable and it felt like you were trying to interfere with their relationship'

I don't get what the 'blackmailing' part of that is about

Yeah, people also sided with the riley person and didn't even listen to your side of the story Not just that. People keep on listening to one side but not the other, its not good but thats what they really need to improve on
