Hi

I"m sorry to hear about everything going on in your relationship. It sounds very familiar to me and to many here. So you have discovered BPD. Your H has stated in the past that he will not get counseling and thinks there is nothing wrong with him.
What would you hope to gain by telling him he has BPD? Do you think this will cause him to get help or will he continue down the path of refusing help? Will he hold the fact that you think he has a mental illness against you?
We have a lot of great resources listed on the right side of the page that can help you begin to change the way you approach your relationship, your communication, and taking care of yourself. I think a lot of these will really help you. We have a saying around here: You can't make things better until you stop making them worse. Even though the way our partners act towards us is not our fault, we have also contributed negatively to the relationship. This site will help you begin to fix those things in yourself that are in your control. I highly suggest you check them out.
To get you started here is a link to one of our workshops on whether you should tell your pwBPD that you think they have BPD:
