Ex gf who confessed her love to me many times is having a mental breakdown. She has had them before and always asked me to be there for her in the past.

>she contacted me 6 AM and 8 PM
>i didnt get notifications, I was busy at the time, my mom was sick
>she deleted them and blocked me cause I didnt read them in time
>I apologize, she immediately blocks me on another platform
>she starts deleting/blocking all her lifelong friends over the next few months, I get blocked too
>she has no one left, a barren profile with no profile photo, no posts
>I try to reach out and inquire what's wrong

She tells me that if I contact her again she'll call the cops on me.
At this point I cannot contact her anymore. She has always been a little crazy, that's why I broke up with her, which she resents me for. But I was afraid she was gonna self harm. I've heard too many horror stories of people not reaching out to people in times like this and it ending like that.
I just find it really strange she cut off her female best friends that she cherished. I wanted to save her.
Has anyone been through this?

I don't understand why people keep up with their ex-whatever. It's over, just delete that person from the empathy center in your brain.
