Welcome to this site. Yes, you found this for a reason. Most of us will tell you that it is not our place to advise you to divorce your husband. But, all of us will tell you that his affliction, his "disease" is one that is known to be progressive. This is what I see in your post:
* you said "I'm done"
* you said "I fear each day"
* you said "the lies are killing me"
* you said "I feel like I can't do this anymore...I want out
but also said you don't know if it's right. Let's think about that piece - what about you getting out would not be right? There could be a lot of answers; just wondering what yours is.
Your husband clearly does not wish to get sober. I hear him shouting it from the rooftops. You can lead a horse to water, but, as you are experiencing, cannot make him drink.
