Oh Kitty, I cannot imagine having that hurt and pain wedged there, over the years.... I have an older sibling, and there have been times when I've been upset that they didn't notice what they said or did. It gets worse remembering or expecting them to be truly remorseful, no matter how much time has passed.
None of us deserve our pain to be invalidated or swept under the rug. We need to be heard. We deserve to still be angry and what's heartbreaking is when there is a desire to move on, but no genuine effort from the person you want to hear the truth come from.
