Hi Horn,
Great job on day three, glad you are using SR as a support. Realize that your emotions are all over the place at this point too. Give yourself some time to work on sobriety, and then take some time to work on your marriage. Maybe counseling would work, maybe you will be able to talk to her about how you are feeling. Marriage isn't easy, and maybe things will not work out, but you need to give things a little time before going there.
