Oh, Yes, I can relate to the lying thing! It seems that the farther the alcoholic gets into the disease....the worse the lying gets.....
I think so too, until they literally don't know what's real and what isn't. My ex-abf, back in the day, spun the most entertaining tales about all sorts of things. Like stories of his service in Viet Nam (yeah I'm dating myself lol). All total bs. But he'd gather an audience and be very convincing.
After a while it seemed he really believed it. It was creepy. Yet I hung in there for four years. I guess I believed my own lies too "my love will cure him, it's not that bad". Until it was that bad.
