Our diocese has a program for "Single Again" adults, but it is focused on reintegrating divorced, widowed, or separated people back into parish life and dealing with the grief that follows the breaking of a relationship.
Sounds like you're way past that. You ought to check into what your diocese has to offer, if anything. You're right, though. There don't seem to be any ongoing efforts to help those going through annulments get their questions answered or just be able to vent over the length of time, and have that dealt with, too.
You've given me an idea..................
We have a priest from the Chancery coming to talk at our parish on April 13th.
We blazed "Annulments" across the top of the flyer we inserted in the bulletin.
Teens (and parents, if they so wish) and young adults will watch a video on Dating and Chastity and then proceed with a discussion.
Childcare will be provided and Friendship activities offered for all of them.
(Just what one little parish is doing to change this deplorable little gap in ministry.)
Actually -- it is a pretty big gap!
