I have a friend who I am increasingly convinced suffers from a personality disorder. She isn't a horrible person, but she lacks any capacity for empathy. She doesn't mean to be selfish, but she is so utterly self-absorbed that she has no capacity to give as well as take in a friendship or a relationship.
She cycles through a pattern of starting relationships with nice men, and then exhibiting increasingly controlling and histrionic behaviour, which pushes them away. If she doesn't get her way, her behaviour is off the scale - she will literally lie on the floor and beat her head against it, while crying hysterically. If asked whether she thinks this is normal, she'll say it's 'just her' and her bf should love her 'just as she is' (yes, really). No amount of trying to get her to examine the unreasonableness of that has any effect. It's like she lives in a melodrama, and having drama in her life is more important than having stability. I've seen her relationships start and end the exact same way four times in five years, and every single time I've been the one to pick up the pieces.
I don't know why I'm doing this, because I never get anything 'back'! It's like somehow the fact that she's hurt and vulnerable makes me feel a need to care, despite the fact that I know rationally she only ever calls when in crisis, she never contributes anything positive, and that what appears to be a 'ground zero' psychological event for her actually passes very quickly without ill effects. I've been having a rough time myself lately, and she is far too self-involved even to notice -and when I explained to her the various pressures I was under, she was completely uninterested. Despite the fact that I should know better, I was hurt by this - which suggests to me that perhaps I need to examine my own reasons for putting up with a one-way friendship like this (which I don't fully understand myself!! Why am I doing this?)
AIBU to cut contact? Should I offer her an explanation, or should I just leave it?
