Hi AchingWife and
Family dynamics when both BPD and kids are involved are so difficult (my husband's kids' mom has many BPD traits). It makes sense you're really weighing your options and working on educating yourself and trying to make wise choices.
It sounds like the two of you don't have any shared kids? How old are his, and how are they coping with your H's behaviors?
What behaviors of his worsened? And have you heard of the concept of an
"extinction burst"? I'm curious if you think that might be what's going on with his escalations after you made different, healthier choices for yourself.
These are not easy decisions so we're glad you're talking through things here. Looking forward to hearing more from you;
