Even thought what I think was the trigger was a few years before BD, I think he was actually in it for a very short time before BD, a few months maybe. But it has now been years, and he has gone back to the beginning at least 4 times, changing OW each time. So he's never been in any one situation long enough for it to become real.
I've thought several times during this that ok, now he's made some decisions, and so on, and have been wrong every time. Even just recently I thought he was being rational, etc., and was pretty shocked to discover that no, he's STILL avoiding. He's thought nothing through. It's been 5 years since BD.
