hi Bbqcharie and
i'm so sorry about your situation and you will meet posters here who will be able to understand the confusion that being in a r/s with a person with BPD can bring.
I don't know how to offer him help or counseling without sounding like I'm accusing him of being crazy.
it can be very hard to broach the subject of BPD with partners. because of the nature of the disorder, in which the pwBPD will hear almost anything as judgemental, even kindnesses, it's usually advised that you don't name it, unless your h himself acknowledges his patters of behavior and wants to seek counseling. (we have a reading on this topic here:
Article 6: Helping a Loved-One with Borderline Personality Disorder Seek Treatment.) a good place for you to start would be with the readings on the right hand side of this page, "The Lessons." they've been prepared by top students of BPD.
do you have support for yourself? do you have a counselor or friends you can talk things out with? plese keep posting Bbqcharlie!
