This post describes quite accurately what happened to me and my marriage.
I was an enabler, but not of an physically abusive husband, not of an alcoholic or drug addict, not any of these bad things. I was an enabler of a man addicted to adolescence. I forgave his adolescent behavior so many times that I came to expect the behavior and became numb to it.
Instead they said, "It's not so bad. He could be an alcoholic."
Although I felt awful, I knew I couldn't help him. I had tried for 31 years and had been unsuccessful. I needed to remake me. As it turned out, I probably should or could have left sooner because he has been able to take care of himself, possibly because he must. I am concerned though that when his money runs out, he will be knocking on my door, but I have steeled myself to enable no more.
