Insidious abuse that's hard to understand

I didn't realise until over a year after the separation that the relationship I had been in for almost a decade was abusive. I was confused, I was lost, I doubted every thought and memory I had because that's what I'd been conditioned to do. He used to tell me I had a bad memory, that I remembered the incident wrongly; he would start an argument in the car on the way to what was supposed to be a pleasant gathering with friends; he would criticise me all the time and when I finally snapped and shouted at him to stop criticising, he said I was crazy. He didn't let me sleep a full night for 4 years after our baby was born, I was exhausted, I was extremely anxious about everything. I was in fight or flight mode all the time. The last straw was him shouting at our child all the time because he made a noise, because he made a mess, because of something. I know all this now, but I didn't understand what was happening at the time. I will still second guess myself if anyone vaguely questions my choice or my decision. I was strong before and I lost my voice. I'm fighting hard to get it back but post separation abuse is real and it's difficult when someone is constantly trying to invalidate you and dismiss your concerns. No more. We have to talk about it, join together and eradicate a permissiveness that allows victims to be suppressed and perpetrators to continue unchecked.
