Are you advocating dating his wife *while* she's sleeping with the OM? Not sure that gets him what he wants. If I was unmarried in what I thought was an exclusive relationship and my SO told me he was going to date someone else, I'd have to reevaluate my life in terms of what is good/healthy for me.
I agree with bringing more love into the R, but not at personal expense. It comes down to what Sinclair is willing and able to do without cost to his well-being.
It comes down to the airline adage: "Put your own mask on first."
Do what is necessary to keep yourself well first, then reevaluate. It *is* possible to do this without damaging the R.
