The silent treatment is the absolute worst! To me it is a spirit killer, and I'm inclined not to play that game. My best advice is to restructure your life and find your independence caring for yourself.
A rebound boyfriend is not recommended, but work through your own issues and get healthy, staying sober, maybe visiting some of your Codie issues through Al-anon as well. Until we get healthier we generally do not attract "normal" balanced people. Please don't expect to meet them through a bar or pub!
Stay strong! Best wishes for you as you start your life as a strong independent woman!
