We argued back and forth about who is being abused here but it goes nowhere.
This was likely the goal. Although I don't want you to think it was a well thought out goal or even one she could express.
Emotional handicap is a good way to describe it. Very likely in her past she started to associate "arguing" with someone being emotional or connected to her.
So, when she gets weird feelings now, she "goes with what she knows" and looks for an argument about whatever. "Abuse" just happened to be what was
hooking you and getting you to stay engaged... .so she went with it.
Very important that to take a step back and see the big picture.
She is attempting to "hook" you in to a conversation that goes nowhere.
Don't get hooked. You don't have to convince her. Just avoid the hook... the bait... .whatever analogy works.
One way to avoid is to validate and the pivot to a solution. Letting her solve her things.
"I can understand how you feel that way. What do you plan to do about it?" Key to keep voice even and not get "worked up".
sometimes it is good to be interested but too busy to deal with it now. Especially if she tends to ramp up and down quickly.
"Hey... .this sounds really important to you. That makes it important to me. I'm available to talk more about this in an hour. I want to be able to give you my full attention."
You'll have to play around with what works best.
Remember: Don't get hooked.
