Such a sad story, and no less sad for how common it is. Men do this, in part, just because they can. As long as there is a vast disparity of power between men and women, that power will be abused with impunity, and women will continue to be trained by patriarchal institutions (beginning with conservative churches) to accept it.

I hope you will find a way to embrace and employ the strength that has enabled you to survive all this, and claim the future you deserve.
