While there are plenty of support groups for the divorced, the majority of them take place in Christian churches. This does not always mean that the group is religious – you will have to call and check or even investigate to see. Also, groups tend to come and go. Please send a note if you happen to know of any Pagan-focused divorce support groups.
Since the 90s, this remains the one page you can consistently find something to connect you to other Pagans.
