There is no black and white answer to your question. Everyone here has an input and you need to sift through them and find what works for you. Sometimes it's as easy as throwing your spouse out on the street to make them realize what they have lost. Other times you need to give them space in your home to "show" them what they may lose. Your situation is not your Wife’s fault. She did not do this on her own. You both had a part in it. My W had an affair. Yes the affair was wrong but something drove her to this point.
