Yes, sorry to say it is progressive. When I first came to SR I was asking the same questions as you. At that time my AW was drinking 1/2 to 3/4 a bottle of wine everyday. Now, a couple of years later she is up to 1 1/2 bottles a night plus adding some hard liquor for that last added bump into oblivion. Not only is her tolerance getting progressive, her total self as a person continues to spiral downward. She has an increased sense of self loathing, perceptions, suspicions etc that all get magnified when she is drunk. The blame game has also progressed. Until lately, our children were off limits of who was to blame for all her problems in life. But as of late, even they are being pulled into the cesspool of her toxic rants.
