The thing is, you cant make someobdy "change back" no matter how good you try and become. When a spouse dumps you they really just cant stand it anymore and their mind is made up and there is no changing back to them and if they do reconsider, it takes a long time and really, they need to be on their own first to really take a second look. Once the affair happens it really is tough. Not impossible, but tough. Its all too late for them. But its not too late for you.
