My spouse has been consistently riding the emotional roller coaster since August 2021. Just wondering what's going to come first, her regulating her emotions or the divorce she's adamant on?
It's impossible to say if or when she will regulate her emotions. You have no control over this.
pwBPD often don't make significant decisions or take significant action on their own. They seem more likely to wait and let someone else act. Then they're "not responsible" for the outcome. They can also be unpredictable. You have no control over this either.
What's the longest dysregulation time your pwBPD has experienced?
You'll probably get a wide range of answers to this question. My uBPDw recently went for about 3 weeks straight. That was a non-stop record.
It's been a cyclical dysregulation since August... I'm painted black for about 25 days out of the month, then the sun comes out and I'm back in good graces for about 5 days, intermittently throughout the month. This is the longest amount of time she has held on to wanting to divorce me.
In that sense, for my W it's been more like 1.5 years at this point.
But if your question has more to do with how long you want to hang on and wait for something to change, keep in mind that you're the only one who can make change happen, whatever that change may be. I'm paraphrasing what BifOof wrote.
