The unkindness

Have been wrecking my mind to understand why my ADD ex partner was so unkind in the end. All the terrible things he said and later confirmed. The best explanation for most of his behavior has been that he was trying to avoid fear and shame. With this unkindness, I struggle to make that connection. It was so destructive and hurtful. But what did he gain from it?

Was he trying to destroy everything completely so there would be no way back for us? Did he want to destroy me? Was it revenge for feeling intimidated by my over functioning?

Is this what people do when they divorce?

It's a year ago but people, I'm still heartbroken.
