Hi Sunflower@garden1,
Welcome to the forum, thank you for sharing with us. What you’ve described is very common for women who have been through domestic abuse. Both the not realising it’s happening while you’re in it and it taking time to recover. Hopefully some of the other women here will be able to share their experiences and what they’ve found helpful soon. You might like to have a look at the Bloom website, which offers courses and other resources to support with healing from trauma, including specifically around abusive relationships.
Take care and keep posting,
Lisa
