Hi yellowwarbler,
Welcome to the BPD Family
I'm on these boards because my significant other (SO) has an undiagnosed BPD ex-wife (uBPDxw).
I can tell you what I did when I first discovered BPD and that was to hit my local library and read everything they had on the topic. I've never regretted doing that it gave me a good grounding in what BPD is.
A couple good books are... .
Overcoming Borderline Personality Disorder: A Family Guide for Healing and Changeby Valerie Porr
and
Stop Walking on Eggshells : Taking Your Life Back When Someone You Care about Has Borderline Personality Disorder by Paul T. Mason and Randi Kreger
I also want to point out the box to the right ---> each item is a link to more information. You might want to start in the "Lessons" section.
Besides learning what you can about BPD, I would say hang out around here. Everyone has someone with BPD in their lives, we all get it. There is a ton of information, tools and support to be had here.
Can you tell us a little bit more about your story? How long have you and your husband been together? Any Children? What kinds of behaviors are you seeing? What do you struggle with most?
I look forward to hearing more of your story.
Again Welcome
