My husband has finally been diagnosed with BPD traits after years of struggle. Trying to find counseling for myself and for him is extremely difficult. I am mostly looking for understanding and empathy since I can’t get that from him. Out local NAMI group is all parents and grandparents - no spouses. I feel isolated and alone.
Hello and welcome. It is very tough finding the right counselor, but there are tons of resources available online to narrow your search.
You can find empathy here since all of us have walked the same path in marriage and/or divorce. We can also help with the understanding part if you want to ask specific questions about your husband or BPD in general.
To give you the quick, generic answer though, BPD is a mood disorder that makes people feel intensely...whatever feeling they're dealing with. Combine that with low self-worth and a fear of abandonment, and it creates a recipe for disaster in all close relationships. Someone with BPD might "latch on" to a feeling and try to analyze it deeper, which sends them down a rabbit hole of past events that may or may not be remembered clearly or objectively.
Suddenly you saying, "Did you remember to take the trash out," is an attack on everything he stands for as a person, because disordered thinking has created a reality that looks nothing like the one you live in.
So how do you "fight back" against BPD? Love and compassion at the right moment can divert the worst of it if you know what you're looking for and have the strength to avoid being sucked into silly arguments about absolutely nothing at all. If he's mad, acknowledge that and be an ally...what happened to make you upset? What can I do to help? If he's sad, give him a hug and remind him that you're there for him. Sometimes it really can be that easy if you catch it up front.
Why? There's a term called "splitting" associated with BPD, where someone is viewed in black (bad) and white (good). So by giving healthy reminders that you love him, you support him, and you're the #1 person who advocates for him, you go from being labeled black or grey to his one white knight. The more he feels like you understand him, the less he'll lash out in frustration.
I hope that helps as a starting point and again, welcome to the family!
