For some of us having short term affair or friends with benefits, is a short term solution while we wait on our spouse to hopefully get back to us. And if they don't, we have already rebuilt our life.
So you feel that stooping down to your wife's level (after your numerous posts about how heartless, unfair, hurtful, etc etc her behaviour has been) is actually "rebuilding your life." Reality check, please!
As for your spouse "hopefully getting back to us"--you do know it ALWAYS takes two to make that happen, surely. And your own affair has just made that a whole less likely.
