Does anyone know why pwBPD can’t look at important people in their lives when they are splitting?
Their emotions will be running wild during splitting and their BPD causes them to run away from problems rather than face them, so they literally turn their face away from you. They're probably feeling shame and guilt deep down too, which also makes them not want to face you.
My ex would never look at me while I tried to soothe her outbursts - I can remember trying to talk to her and she would just be staring off to one side. On rare occasions I was able to talk her round and she'd then look at me again but it didn't happen very often.
It's nothing you're doing wrong, it's just a part of their illness that makes them withdraw.
