I have seen many articles by Leslie Vernick on the topic of destructive and/or dangerous marriages. I appreciate her work. I recently discovered this link to her month long series on domestic violence, with daily articles and videos. I may not agree 100% with everything she says, but I know you will find her site to be quite helpful. Domestic Awareness Violence Month
Please also visit my own Domestic Violence Resource Page which is full of links to my articles and other sites.
