Yes, I did. I tried to limit the questions, and only asked them very early on in our reconciliation. It wasn't a complicated story -- my wife and I had grown distant, stopped ML (I stopped initiating, after years of a SSM), and stopped complimenting her (her primary LL is WOAs). OM made her feel like she "mattered."
We will occasionally talk about OM, or those times, but only IN CONTEXT to something going on with us -- I don't just bring it up out of the blue.
I do wish, however, that we had talked about it MORE -- with an MC -- as we reconciled. I do still feel like there are some unresolved issues there.
