I just read what GalaGirl wrote. I couldn't have said it any better, even if I spent the next hour trying to. I will add my own short, blunt 2 cents. You lied, cheated and betrayed your wife. By doing that you created a mess. Now, you're complaining about that mess, and trying really hard to find a way to make yourself look like the victim of that mess.
Yes it is that simple to fix. You just don't want to do it. You're trying to say the cheating you did is not as bad as it sounds because your wife now says go ahead and be with Chris. That sounds much better to you than fixing this the right way. It sounds to me like you are not interested at all in doing the right thing. I hope you change your mind.
