The next day, the dude texted her threatening messages about how he would make her suffer if she didn't give him a reply, I was like what the fuck?...Now that's serious.

Its very unfortunate how some of our guys act towards a girl this is why ladies need to be very careful before being submissive to a guy. I have seen these similar case with one of my female friend as well and she escaped death in the hands of her fiance when she didn't know the kind of guy he was.
