MDA, thanks for stopping by and I wish you success.
GH, you can think that I'm still DB'ing if you want, but I don't think this really qualifies as setting boundaries. "Boundaries" refers to behavior that you will not accept from the spouse.
My saying that I'm not really interested in taking her back unless she has a true religious conversion, expresses a willingness to have more children, proves to me that she would be a much better mother than before, and by the way quits the job she loves that keeps her on call every night until after 9:00 pm so that we could have some family time ... well, that seems to me to be a little more than setting boundaries.
It also seems unlikely, which is why I'm no longer hopeful for a reconciliation.
The LORD is near to all who call on him, to all who call on him in truth." (Psalm 145:18)
