This is always where you lose me, Neecy (not just YOU, but others on this forum as well). I know we are all very different, but I have a hard time understanding why anyone would want to date their cheating spouse. Additionally, when the cheating spouse gets that need -- for recreational companionship -- met by the betrayed spouse, it enables them in their inability to make a decision.
At a MINIMUM, I think you should wait for HIM to suggest it, so you can give it an uninspired "Sure -- sounds like a plan" or some such.
