Was your whole married life a sham? Probably not. Take some time to think about some good experiences that you had together, some experiences that show that you have known happiness and fulfillment and pleasure in your married life.
Next, to reinforce your conviction to get out or that you did the right thing to get out, remember some bad occasions. Remember when your husband violated the sovereignty of your soul, when he made you cry and question yourself, when he was not your Prince Charming.
Remember the good and the bad. Don't deny the love, but don't deny what was done to violate that love, that trust that you had in him. He cannot be your soulmate if he makes your soul curl up in anguish.
