OK, here goes. Let me go with the most recent meltdown. It has something to do with the previous meltdown. But first some background. I apologize if this is to graphic.
Sometime in 2019 I talked her into buying a vibrator. I promised her I would give her the $$ back. But
PLEASE READ happened in the ensuing time. In November 2019 she went on a leave from school so she was no longer in the Bronx. She lives 60 miles from me so us meeting was already difficult outside of the Bronx due to among other things her husband finding out about us in April 2019. Plus, when COVID came along we were teaching from home, etc... so it was difficult to get her the money.
In February I fell asleep one night and didn't text her. This led to a minor meltdown but somehow it led to the bigger meltdown of the cash for the vibe. All of the sudden after 2 1/2 years whammo! Yes, I have issues with following through. I am ADHD and I have tried to tell her and have her read about adult ADHD to no avail.
So I get "I can't use it knowing you didn't give me the money as you promised." Even though she wasn't on top of it as well. I just got insanity on the phone, she wouldn't let me get word in edge wise, screaming at me over a vibrator, etc..
Anyway I go to meet her after school, I have $20 in my pocket I try to give her the money and she says no. I say "OK, I'll run into bodega and take the money out and you'll have it in 30 seconds." She drives off. She blocks me on FB. I email her letting lose. About how she lies, about that she is BPD, she needs help. Etc...
That lasts a week, and we're talking again. There is a district wide Happy Hour March 25 and I tell her she'll have the money then. By the 25th I couldn't get the money and was hoping and praying she would forget. Yes, I should have told her beforehand but honestly, I am and was afraid of a meltdown. But I promised to get her the money this week that we are off.
March 27 she texts me telling me she's thinking of me sending me the most erotic photos of what she wants to do with me. The next morning we are talking on the phone and I can tell she is in a bad mood and she brings up the $60 again. In less than 12 hours she goes from wanting to b**w me to hating me and yelling at me.

I say I can't deal with this and I'll talk to her in two weeks (this week) when I come with the $60. She texted me a few times again that day chastising me etc.. I ignored her and then she blocked me.
I can't take this
PLEASE READ anymore. There's a lot more I haven't shared. She's like a drug.
What gets me is that she doesn't see how her meltdowns are destructive. She doesn't even see these as meltdowns. That she says I treat her bad yet when she does this time after time to inane bull
PLEASE READ she doesn't see how this affects me and my mental health.
