Welcome BPD Spouse: I'm so sorry that you have a troubled relationship with your husband. You say that he has had two major depressive episodes and there is a family history of some form of Bipolar illness. Is your husband currently getting any treatment for his depression (meds and or therapy)? I understand that you husband has not had a BPD diagnosis. BPD generally doesn't stand alone. Most people who end up with a BPD diagnosis, generally have had symptoms of or a diagnosis of depression, bipolar, anxiety, PTSD, ADHD/ADD, OCD or other disorders.
We were separated for 13 months a little over a year ago. I left because he was acting out and left me no choice. He then decided that "losing me would be the biggest mistake he would ever make in his life", so we agreed that I would return, and we would both work to rekindle our marriage, the old, "I love you, but I am not in love with you". I am hoping to hear from those of you that have had similar experiences.
You say you both agreed to work on rekindling your marriage. Your posting here is a good step forward on your part. Is your husband willing to go to couple's therapy or work on learning some skills to manage his emotions better?
It isn't necessary to have an official BPD diagnosis, to make things better. There are lessons here on various communication skills that can be helpful in all relationships. These skills can be beneficial, when used with someone with a personality disorder.
A good place to start with some skills is to
look in the right margin and go to the middle area where there are links to "Basic Tools". Some people like to come back to post about various skills, once they have studied them. It can be valuable to check your understanding and gain support on how to use the tools in various situations. It takes some practice, but once you gain some confidence in using the communication tools, it can make things better for you.
