Aggressive upon rejection?

They believe they're entitled to a part of you, which is not only shitty but also predatory. If you're lucky they can't back up any of the shit they talk but when it happens in person it's pretty scary whether they seem overtly threatening or not. I'd be careful because I've been stalked both online and in person so anonymity is important and you were smart to keep some.

Not gonna go into details but today my coworker was having a bad day because of a toxic relationship of this nature and her boyfriend was harassing her through text messages. Then she blocked him and he continued on messenger. Then she blocked him there too. I would recommend anyone not to show their private messages to other people like this, but she wanted to show them to everyone and the guy was insulting her in every way he could think of, even her family, even trying to isolate her from her friends like "I talk to Bob about you and he agrees you're retarded" and that conversation with Bob probably never happened, etc. I think people that do that do it for revenge. They know they lost and won't get what they wanted anymore. It's gone, sex is out of reach. But not without a fight, and they will try their hardest to cause as much damage as possible. It's not like it can get any worse from there from their perspective.

I certainly know of these people, but can't say I have direct experience with any of them. Most of them are probably control freaks that wanted a relationship to have a possession or prize, rather than an actual partner or anything meaningful. My only personal "rejection" story (if you can call it that), was way back in high school. Had a girl ask me out and publicly held my hand around school. This went on for about a week. Turns out she did it all just to make her boyfriend jealous. Me being a fragile guy, was very hurt and it effected my perception of relationships (and my chances in one) for years. It was the first time anyone had ever asked me out, and it was simply to use me.
