Not one bit, and that's the sad thing.
When I was 23 and left my physically abusive husband (whom she never liked anyway), she came to visit me in my one dingy room, shared bathroom and kitchen accommodation I managed to rent from work, and the first words out of her mouth were "who's the other guy?". There was never any other guy!
She was living in a three bedroom flat by herself and never offered me a place to stay.
THEN, to top it off, she became his best friend for a while!!!! She loves to move in on people when they are upset and he was very upset. Floods of tears and carrying on about how I'd just walked out and left a note (I did this because I was so afraid of his rages).
I didn't appear to be falling apart, but that's because I did it in private. I learned as a child never to let my mother see me suffer, as I believe she enjoys it.
I expressly asked her not to reveal my address to my violent ex and she did.
So no, my mother doesn't even register when life falls apart for me. Not at all.
I am happy for those who have that kind of backing and love in their lives, I really am. Must feel great.
