I will be very happy if your story ends with a happy end. But I don't believe it at all. Some miraculous healing of the husband of a despot who used physical violence for three years.
I never tire of repeating that such stories, even if they exist, are the fault of the survivors. Almost 100% of these stories will end very sadly. It will end with broken destinies, broken lives, broken psyches, and sometimes even terribly, because we all heard about domestic murders.
When my ex-husband raised his hand to me for the first time, I forgave. And when I did it for the second time, I spent 8 months to persuade him to give me a divorce
