I have to put my two cents in here. I am diagnosed bipolar 1 and I have a IUD so no periods. Before I was diagnosed or medicated, I would get were I hated my husband. I thought our marriage was so crappy. I would fight with him all the time about nothing and leave for months on end. Then I would think what am I doing I love this man hes a wonderful father and husband.. Sadly I have left him about 5 times in a 10 yr marriage. I am happy to say he is still standing by my side.. I also have not left him since medicated or argue with him at all really. So in my experience it is BP related.
