What about trying to write out what you want to say before you say it to your W? Actually typing would be better, so that you can go back, read it later, and edit. I think you are right, you need to confront. But remember there is a such thing as constructive confrontation. I understand your anger, but remember what your ultimate goal is. Whether it is to end things, or try to continue to make them work, remember you have tried. Dan, you are great, and you will get through this. But think first what you want the end result to be, and plan accordingly.
