Just been reading your sitch and the wedding ring thing is right where I am.
She kept hers on post BD for a while but after a couple of months she went much colder on me (likely OM) and took it off. I still wear mine a) out of habit and b) to show my intentions to anyone else who is paying attention.
I’m starting to feel like it may be time to take it off but, whether W does or not, I believe in the sanctity of marriage and that it isn’t over until it’s over. Maybe that’s hopelessly naive and shows that I am still to attached, I don’t know.
Anyway, good luck, brother. Keep up the good work.
