I wonder if there is an element in abuse where you could say “they really can’t help it”. That’s not to say it’s excusable in any way but just to confirm that change is almost impossible for them.
Those who become their victims have to see that and fight to understand that WE can never change them. Once we get that, we have a chance of escaping. We haven’t got the luxury of any more pity, as that is the leg-hold trap.
With a bit of distance, maybe we do have the luxury of pity, when someone else is the punching bag, not us. And just maybe there’s a rush of affection for someone who just can’t help themselves? Combined with nostalgia for the good side of these relationships, which, let’s be honest, is, or was, really good.
I don’t know whether there’s something there, what did you feel was at the root of your feelings?
