"How could you have done this to me, to us? Who are you and who did I marry?" With tears in his eyes, my ex-husband shouted and screamed these questions at me on the day he found out that I'd had an affair. All the while, I stood there shaking, in shock, not knowing what to say that would make what I had done right. I was a cheater. Looking back, I realize that nothing in that moment would have given him the solace and comfort that he was looking for — or that I was looking for.
