I feel no desire to rescue him no matter how dismal his situation were to become, and I know that is not out of healthy caring for myself and my recovering codependence, but rather the last remnants of bitterness over his choices and how they affected our lives.
I'm not so sure that being bitter and angry are unhealthy, actually. I know feeling no desire to rescue isn't. It's taken me a year and a half of a lot of emotional pain to get to where I am finally OK enough with his disasterous life decisions to be able to get on with MY life regardless...and I think if I would have felt MORE anger with him and the situation sooner, I could have maybe spared myself some of that pain.
