Hi catlaus,

I'd like to welcome you to bpdfamily. I'm that you found that the video helpful in answering questions for you that you probably has going on for a long time. Why does she act this way? What did I do to trigger this response with her? When are things going to get better?
I'd suggest to read as much as you can about the disorder, it's really helpful in a couple of ways. It helps normalize the behaviours, make sure that you read from trusted sources with accredited medical information. It will also help you with deoersonalizing the behaviours.
When your spouse turns into the Mr Hyde persona, it's not personal to you, it's maladaptive coping mechanisms that protects the ego from anxiety and stress. It's something that your pwBPD is going through.
What prompted you to watch the video? Is there something specific that brought you here? How long have you been together? Do you have kids?
