Heart breaking rift

My dad and brother spoke. My dad told him how hurt he was at my brothers words. He was quite shattered really. Huge blow. He had thought he was my brother's hero and to find out what he really thought of him hurt.
My brother said sorry many times. His sorry many times is.. in my opinion and experience... not really a sorry at all. More of a desperate way of stopping what is hurting or painful as quickly as possible. And indeed. He seems happy not having my parents over. He speaks normally to my mum about other things.
My parents now feel that he thinks they aren't good for the child. That hurts them. The fact that he knows how he hurt them and is doing nothing to alleviate their hurt or to make amends or build bridges that involves them seeing Deepa is really hurtful now. They can't pretend he doesn't know . So they have to accept he knows and doesn't want things to change.
That's painful.
All they had was concern for deepa and now it looks like they may not get to see her again!!! I hope it palls over. He is not one to genuinely apologise. He wont. But... to keep them from their beloved grand daughter... They must be strong. I love them. The whole world loves them looks up to them. Their own son treats them like dirt and dangerous scum around their kid! Such irony.
Kanna has no idea how lucky we are to have had our parents as our parents.
Maybe one day he will know the pain he caused them and feel truly sorry.
