Hi Falling Feather, I join Rive3rW0lf in saying Hello to you.
It's understandable that communication would be a challenge in your marriage. I agree with RW and you, it's very positive that he suggested going to MC, and you deserve kudos for being willing to go and do the work.
I want to give you a heads up that this site is tailored more towards people who don't have BPD and are working on relationships with someone who does have BPD or BPD type traits. The way struggles get talked about here may be less supportive to someone managing BPD, like yourself, than a site that is geared towards members with BPD. I would not want for you to run across a post or thread that is destabilizing or not very empathetic.
Not sure if you have seen this site before -- I think it is for people around the world, not just in the USA -- but this could be a better fit for your specific needs and growth:
https://www.nami.org/Support-Education/Mental-Health-Education/NAMI-Peer-to-PeerThe brief description below reads:

They also have a page about "disclosing to others" and my hope for you is that if you haven't seen it already, that it provides meaningful suggestions and support for talking about your MH journey with your husband:
https://www.nami.org/Your-Journey/Individuals-with-Mental-Illness/Disclosing-to-OthersWe 100% wish you success and a positive, healing journey together with your husband. I hear a lot of positives and I think there is hope for you two as you add more skills and tools to your "toolbelt" and grow together.
All the best;
