It goes without saying that I broke up with her immediately. Why do people pull shit like

What a cunt. I hate bitches that do that. I hope OP dumped her ass

Judge at the murder trial: “You’re free to go, i would have done the same”

My best friend waited for marriage to avoid all this crap.

to the OP: Why did she think the two of you were getting ready to break up? Had it come up in conversation? (Yeah, I would have almost certainly dumped too her if she pulled that on me.)
