Yes I experience that with my BPDbf as well. He is in therapy for years and actually learned to be open with his feelings and puts a lot of effort into communicating them. But a lot of people still fail to grasp the extent and intensity of those feelings. They don't understand that cancelling a meet up causes him to feel deeply rejected and unimportant, because with a non this wouldn't be a big issue. If he expresses his frustration and tells them that he can't deal with that, they get annoyed and defensive. No compassion, no validation. I don't really blame them, because somebody who didn't put some time into researching BPD will probably not be able to really get what this is all about and misunderstand his reaction as intentional, overly aggressive and dramatic. This happens a lot and often causes him to feel miserable for several days even if I do my best to validate and help him get over it.
I would love to be able to have deep conversation with my wife about her deep seeded fears.
Should it come to that and depending on your wifes history be prepared for things to get pretty dark and depressing. Everytime my bf tells me about his inner life, his childhood experiences or daily struggles I get a glimpse of the immense pain and sadness he is feeling everyday. And there is nothing I can do to help but listen.
