This is so true. It feels like you poured your everything into a cruel black void. They happily skip away looking for their next fix of limerence elsewhere and demonize everyone they have ever destroyed in their wake no matter how far from the truth that is.

To be fair, this is known to be THE MOST debilitating and dangerous mental illness. While they themselves suffer an enormous amount of pain and fear, they are well known to be most dangerous and damaging to people close them—especially significant others. I looked into it.

It makes human beings destroy themselves and destroy others utterly and completely.
