Get the book "After the Affair." It's a good one. My H has cheated numerous times and I'm finally to the point of, if he does it again, he's gone. Because of that, I think part of me has allowed myself to trust him again.
Maybe spending this time with him will wake her up to reality?
Just keep an open mind. You honestly never know what is going to happen. All of this -- your sitch -- may have happened just so you and your W could get to a better place. That's how I've began looking at my H wanting a D and telling me he no longer loved me for all those months. I figure it needed to happen so that we could end up growing and figuring out what we need to do to have the M we both want and need.
