Morning, it's always sad when someone passes away, especially if things are left unsaid. We are all different in our emmotions though. My mums 2nd husband (married when I was 5, divorced when I was 16) played a big part in my life until he left, but he never looked back. I sent him Christmas cards and photo's of the children when they were born, but he never sent a reply. He died in the summer. Yes, I hope he rests in piece and my thoughts are with his new family, but I chose not to go to the funeral. My twin sister, who had never sent a card etc, went to pay her respects, she was treated very well by his new family and was please she went. I didn't regret not going..
Strange old world.
You'll do what's best...Take care.
