Hi BlueFrog,

It's suffocating and frustrating when a partner's insecurities are getting in the way of relationships with people; social, friends and family.
A pwBPD lack a stable sense of self, don't really know who they are and have insecure attachments , a rage that is much of the source of their behaviors. He's attached to his ex and hence doesn't cut contact, the same attachment he has with you.
It's Ok. Many members come here with a lot on their chest and it's not always clear where to start. I can relate
