Don't worry if you don't feel this strong tomorrow, it comes and goes. I feel very sad for you too and I can definitely relate to what you are going through. I decided yesterday that there was really no point in continuing this charade w/my W. We go around acting like a family and spending time together, etc., but we really are not a family. And until she's ready to stop talking to the OM (which she won't do) then there's really nothing for me to hold on to. Anyhow, I found a way to make some extra money, so she can afford to move out on her own, which is what she wants. I still love her very much and I hope that we can work things out, but I just don't see it happening as long as we live in the same house and my feeling continue to be completely ignored. I think you are making the right choice. Your H needs to feel the consequences of his choices. Keep your head up and focus on yourself and your kids.
