Just stumbled on to 3 interesting programs designed for parents in various martial transition situations– ProudtoParent, for parents who have never married, UptoParents, for parents who are getting divorced or who have already divorced, and WhileWeHeal, for parents who are struggling with their marital relationship.  

All of these programs require parents and others to log in, but they are all free.  

Haven’t reviewed these carefully, but worth looking at some more.
