He is on his way down to his inevitable bottom. Picture the addiction like a living screaming demon that does NOT want to lose it's grip on the addict...and as the slippery slope toward the addict's bottom speeds up the demon screams louder and lashes out at everyone around it...ESPECIALLY those that might just listen and help put the brakes on...by listening...absorbing blame...BEST of all LENDING MORE MONEY!
The man you loved is possessed by this demon of addiction. It is just like blair in the exorcist...there is NO reason to listen to him. He is going to try to get you to feel as horrible as he is right now. If he can bring you down, saying untrue gross things in order to do so, then he still has a companion on his level.
Part of the manipulation of an addict is to know where to hit you. If you have any issues around your weight then he will hit you with this one because he knows,that for you, there is some "truth" in it. If he mixes a personal and painful "truth" in with all of the addictive blame and shame and drag then it will all start to feel extra painful and doubtful.
That personal hit is the yeast which makes the bread rise.
ANY CONTACT at this point is dangerous...it is going to cause this kind of re-wounding, painful traumatizing doubt and fear. Anxiety, gut ache. Eventually we learn to not engage. IF he is ever in recovery you simply will NOT be listening to this kind of garbage addict-speak. ANY time he starts to slip into the blame shame garbage it is an indicator of his addiction.
