Welcome to the site, Nova. The information you will find on this site is super helpful in learning about BPD and what that means to a family.
It sounds like a really difficult time in your home right now. Is your husband open to getting therapy or another form of counselling? Has he ever been to a therapist?
I don't know about diagnosing someone without professional help... .perhaps others on the site have more insight into that than I. My BPD husband was diagnosed about a year ago when he started therapy, and the improvements in our relationship have meant everything. yet he refuses to take antidepressants, even tho he was also diagnosed with acute long term depression. I say that to say it is certainly characteristic of pwBPD to not do the things they need to do to help them live better lives.
The sad but true answer to your question is that the symptoms of BPD will never go away. They will always be a part of that person's life. The symptoms are manageable, to a point, but only by the pwBPD. You can help them be in a safe, open, loving environment that can nurture their healing, but a real heart-pull is needed within the pwBPD for things to get better.
My BPDh and I have been together ten years. The first year was normal, the next few years were caught up in teenager rebellion and chaos. Five years ago, he broke his sobriety of thirteen years, and everything went down hill from there. The next four years were hell. With the therapist's help and teaching himself mindfulness, things are better than they have ever been, but I would NOT say perfect.
Loving someone who has BPD is a tall order to fill. One of the most difficult traits to live with is the pwBPD's inability to feel or express empathy, especially towards those they love. It's next to impossible to get any type of support or validation from them - about your feelings, or things that effect you, the nonBPD partner.
That's about all I can share at this point. My suggestion would be to see if he will seek out professional help, if that is an option for you, and I pray he is simply having a hard time with everything right now.
Thanks for sharing, Nova. This is certainly a family here, like the site name implies, a supportive family, and we welcome you.
