My experience and plan of action as well. There are few situations that bringing in the government can’t make worse.
In my dealing with numerous families, I’ve found “Family law” looks to neither law or families. It is automatically a adversarial approach. Even when one or more parties act in good faith, they are assumed to be criminals. I have also never found anything different in “Christian” counseling. They may have a fish on their shingle, but they have the same methodology and lack of privacy.
As far as I know, the only place to find true privileged communication is in the confessional with an ordained priest. I am not Catholic or Orthodox, but I have suggested that others take that route. Sometimes you just need a place where you can speak without fear of retribution.
I know more than one non Catholic who as availed himself of the confessional.
