I think you will both be in a better place over the next few weeks. None of us LBS feel that our WAS ever let us know they were unhappy. However, odds are they were screaming it in the past but we just never heard it. They do not just up and leave for no reason. Reading DR and this forum will really help you come to grips with that. Once you start understanding your own role in your M failing will you be able to work on those issues as well as begin to let the anger subside with your W and understand how she got to where she is now.
Believe me I and every other LBS knows EXACTLY what you are feeling. We have all been there. The best advice I can give you is to listen to the people here who have already walked the path you are currently on. They will offer you wisdom and insight with the true intent of helping you reach your ultimate goal.
Best of luck to you.
