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

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

My ex did this,

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

Why is my vagina swollen, it’s very itchy. I had sex we used protection, but day after it felt like my insides had a heartbeat as well as itching, the pulsing has went away but it is still itchy and my discharge is yellow, i'm 15, what could it be?

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

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.

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.

What's the most trivial thing that ever made you go to the doctor?

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.

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.

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

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.
