If you keep doing the same thing over and over you keep getting the same results. What helped me was to keep the focus in today. It's only today I don't contact him (repeating this every day). Notice that the craving in a codependent is the same as an alcoholic's craving for booze. We both are strongly influenced by denial and rationalization ("I worry about him....he needs support"). Sounds like you need phone support.......I suggest Alanon, where I got the support I needed to get through this tough time.
