I am a little late chiming in on this one.
So far, I've not seen a proper psychologist since my BD, but from everything I've read about MLC, childhood trauma, and personality disorders... etc... I am pinpointing my H as raised by a borderline and having dissociative identity disorder due to childhood trauma. He could be BPD, but that up to him to figure out.
He does LIE a LOT, and he always had.... and not necessary lies either...
It's just so SAD.
He says what he doesn't mean and what he means he does not say.
