Hello and

You're in good company here with other members wanting to improve their relationships with pwBPD (persons with BPD). Often, the ways to improve are counterintuitive, so it helps to get some targeted feedback, as general relationship advice (like "just try to explain yourself better") frequently doesn't help and can actually make things worse.
How long have you and your spouse been married? And do you have any kids?
Looking forward to learning more about your situation;
