The advice is almost always well-meaning, but it’s completely clueless.
“Come on,” the advice goes. “That happened a long time ago. He didn’t really mean to hurt you. They did the best they could. You just need to let it go. It’s time to get over it.”
I know what it feels like to think this about someone, because I’ve done it, too. I remember a conversation I had years ago in which a friend and I mocked someone who couldn’t “get over it” and move on after childhood abuse. That was before I understood my own childhood trauma, so I eventually felt guilty about having said such things about someone else.
But I get it. When you watch someone else go through the agony of long-term pain and anger from emotional abuse, it’s baffling if you don’t have a frame of reference. The person who’s suffered abuse can come across as crazy — at least it can look that way to someone who’s not hurting.

There’s hatred, evil and injustice, but this is the ‘real’ America, too
