Hi Maroon,
I read through the link that you shared. It sounds like you are hedging -- hoping that this shot across the bow (serving divorce papers) is not what your wife wants? You want to save the marriage.
Many of us on these boards have been through high-conflict divorces. Not all people with BPD are high-conflict personalities (HCPs). This is a term that Bill Eddy describes (highconflictinstitute.com) in his book Splitting, about divorcing someone with BPD or NPD. He co-wrote it with Randi Kreger. Someone with BPD is not necessarily HCP, but someone who is HCP typically has a PD, recruits negative advocates, and has a target of blame. Many of us here have been through a high-conflict divorce, and so there is a tendency to treat all pwBPD as though they are HCPs. Eddy wrote an article about what he calls the "theory of pattern of blame" that we have on bpdfamily.
https://bpdfamily.com/message_board/index.php?topic=271911.msg12580077#msg12580077It's really this type of BPD sufferer that causes the most trauma in family law courts, especially when kids are involved. Since you are not likely going to experience a custody battle (if I'm reading your story correctly?) then you will avoid some of the worst of what can happen. However, if your wife is a HCP, then you have to protect yourself from false allegations (child molestation, domestic violence). Sadly, sometimes aggressive lawyers can create high-conflict divorces because they step on BPD triggers and off they go.
I wanted to mention this because some of the advice you get here is influenced by this distinction between BPD and HCP.
Knowing your wife's tendencies, and having the skills that you've learned on the Staying board will help you stay centered. It will go a long way.
If you feel your wife is not HCP, and if you want to delay the divorce process, it's certainly possible to do that! Emotionally, this is complex. Because boundaries are so important. Will you allow your wife to use threat of divorce like this in the future? If she feels victimized, and filing for divorce relieves some of the negative feelings she struggles to cope with, she may do this again. And again.
Your wife may flip back and forth between psychological and emotional reactions to divorce -- that's common for many of us. I left my marriage, but I also struggled with the overwhelming feelings of grief that made my heart ache for someone who I felt was so wonderful, but also so tragic. And my son's father. It is heart breaking to watch our kids come to terms with the end of the relationship. I've never experienced such pain. :'(
It's important, too, that you understand validation, and use these skills with your kids. There are some excellent resources on the Coparenting board about validating kids, including divorced/blended families, young children, teens, and a nice one about how to use validating questions:

I was also so hungry for information during my transition. If you are interested in reading more material about raising emotionally resilient kids (when one parent has BPD), there is an entire lesson devoted to it on the coparenting board:

Do you have a lawyer at this point?
