Wow. This guy is pretty insightful. It's why my second husband's sister was so upset when I "abandoned" him. She and the other siblings had been dealing with him for YEARS. I could do no wrong when I was sitting by his bedside in the hospital as he clung to life after his liver failed. I was the big heroine when we got married.
Once he went back to drinking, and I left, suddenly I was pond scum.
