Why is my ex trying to provoke an argument with me?

I'm assuming she was trying to flee from accountability in her life, probably got caught doing something from the new boyfriend she suddenly had, so to get out of the spot light, she had to put me in it.

My ex did this,

She claimed her friend who was newly single needed her support.

Why are Trump supporters so incredibly stupid?

Eventually the phone calls n texts slowed to a stop. Eventually she stopped coming home. And when she did it was instant anger and yelling.

My daughter from a previous relationship would come over, my ex would leave that weekend n party the whole weekend away. Coming back Sunday. Leaving me with the three kids.

Our breakup process started when she started going out drinking, about when our daughter was 2

What is price of the "liberal celebrities" e.g. Bill Maher, Seth Meyers, Jon Stewart, Trevor Noah, Jimmy Kimmel, Desi Lydic etc. to join the great MAGA movement like Stephen Colbert who wanted to European ambassadorship to turn back on "the Left"?

It eventually became an every weekend thing, then her friend started coming over, every single day. She wouldn't leave. And my ex was letting her invade our life.

So without knowing your situation. I'm guessing your ex had to provoke an argument with you because something on their end did not fall into place as planned, so as a way out. They had to point a finger at you

Inevitably she had an explosive outrage and demanded I moved out n that it was over.

How would you feel if your friend confided in you that she is cheating on her husband, knowing that he loves her deeply? What emotional and ethical considerations would you grapple with in response to her revelation?

Fast forward to 2.5 years later. The explosive anger and aggression came back out of no where. Long texts, picking fights, threats, anger, rage, chaos.
