Well.. at least you know what she responds to: Rap her knuckles, she behaves... for a little bit.
And she really has boundary issues on personal information. I guess it's easier to focus on HER than the family, i.e., her children.
Y'all do love to fight. The former spouse sends me incredibly rude stuff. I'll either ignore it, discredit it using the divorce decree or address it if it's valid. It's a hard thing to do, because it does get me angry and my goat at times.
What stops me? Well one thing is knowing you only get dirty when fighting with someone who's slinging sh!t. And that being cruel and vindicative only makes me feel worse. That little rush isn't worth the spew that comes back or the acid in my stomach.
Next time try not responding to buttons being pushed. Because she's getting what she wants. A reaction from you. That she can still tweak you... hurt you... control you.
