As I have been told by some fantastic posters, we cannot control our spouses. I am taking the advice to concentrate fully on my children, they already have one unpredictable parent so you have to be strong and consistent for them. Please have a look at my posts on the infidelity/affair forum as I have received great advice there in how to deal with my situation which is similar to yours. It is under 'probable affair' heading. While I am not suggesting your wife might be in some sort of relationship, the posts I have received tell me to solely think about the children. I am so glad I have PositivelyMommy contributing to my posts as having a womans perspective on this is invaluable.
We all know this is a living hell but continue with DR, GAL etc and hopefully with patience and consistent actions you wife should see you are a changed man and would be somebody she could come back to. I am by no means an expert on this, I am providing this information based on the great advice I have received.
I am going to try and concentrate on one thing now and that is to be there for my children, to be the best father I can.
