It's the threat of her killing herself. My ex was crazy but not like this. She came out into the garage, kissed me, said "I love you," then popped a handful of pills. Had to call 911. It's scary.
Ok seriously, i get that you dont want your ex gf to just kill herself because you broke up. But toying with the crazy bitch is just making things so much worse. You keep leaving that glimmer of hope that you'll get back together, its gonna end badly
OP, if you are the originator... or tell the originator... Go to the cops and file a report. You don't have to press charges against her... at least have it on record that this the nature of this person. That way, if something does "happen," it won't be that big of a surprise to them.
That's kinda clingy dude O.o sheesh.
