It was a lot like learning a foreign language.
It is a foreign language. People who suffer from BPD process information in ways completely different from the way you and I do. Actually it felt a lot like my Ex and I were always 180 degrees apart. When things felt calm and ordinary to me, and I was starting to relax, things felt empty and void to her and she needed stimulation so she would stir things up. When we were together and sharing I thought oh how sweet this intimacy is, and she thought how absolutely terrifying this is I let my guard down now I will be hurt. When I was troubled or upset, she thought now things have gone badly wrong, I can't deal with this, I will push her away. When I couldn't soothe her feelings she felt I was deliberately holding back and that made her angry.
