ksumm,
welcome to soberrecovery, and the friends and family forum. you are an educated person - if you're at all like me, you will appreciate the wise and caring folks that come here, and the super sharp advice that is given.
what you have just done is HUGE.
you are in the know, with your addictions work background. you are clearly comfortable telling your husband what the score is. yet you have had your own moment of clarity! you have realized - in a relatively short period of time - that you need to change some of your thinking, and behaviors, and you went right to it. i commend you.
i wish you the very best.
