When I was drinking, I didn't lie or cheat or hide it, and I don't remember feeling guilty about anything because in my eyes I was never doing anything harmful. When i got sober, and realized the damage I had done, I about choked on the shame.
I don't think my ex has any idea, he's a sick man and I hope/pray he will get better someday.
How did you come to the conclusion that it is choice and not disease?
