No two cases are the same. My exgf was not
Very dramatic. But Things I dealt with were:

Alcoholic
Bulimic
Self-mutilating
Dissociated and isolated from stress
Walk out during arguments
Lack of education and career
Inordinate focus on social media and makeup/weight/appearance
Impulsive sex (for money) and promiscuity
No close friends
Multiple jobs that ended badly
Silent treatment / cut off with no contact
Moves on very fast to new bf
Not interested in my life; everything revolves around her needs and wants
Intense shame (would be a self critic on her own, acknowledge she is bad)

You just described everything my ex went through. This is off topic to this thread but do you mind my asking how it ended?

I will also add:

Gaslighting
Lies

Ended badly. I broke with her, tried to be amicable. I viewed her social media, observed without judgment she had a new bf. She then retaliated harshly.
