Shirt, you posted this on someone elses thread. It sure sounds like you know what you are talking about.
It is sad how the insanity that is alcoholism trickles over into the non alcoholics that are involved. We are not alone, eventually we will stop fighting so hard for relationships that can not be healthy until the A chooses a true path of recovery. It doesn't mean we don't love them.
No, it isn't easy, but you are right that it is very unhealthy until they choose a true path of recovery. Hang in there and take care of yourself.
