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

My ex did this,

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.

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

Why does my vagina smell sort of fishy/musty days after sex when my boyfriend ejaculates in me? There isn’t any itching or burning when urinating, so I don't think I have BV. It just doesn't smell like me.

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.

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

What if you were the only and last person left on Earth. How will you survive and what would you do with your life?

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.

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

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.

What are some signs that someone may be being stalked by an organization or secret society? How can they find out for sure?

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.
