Clarity.....try to remember that his actions of drinking and lying don't have anything to do with you. He is not drinking "at" you...or lying to deliberately hurt you (although it does)…..It is not personally aimed at you. Alcoholics drink alcohol...and, they all lie about it. It is to protect their ability to drink...of which they have overwhelming compulsion to do. Remember that they lie to themselves, too--as a part of their denial.
Denial of their disease and the seriousness of it is a major feature of the disease of alcoholism.
I reviewed your older threads, and it looks, to me, like he still has several layers of denial...,,still.
Who knows how long it might take him to face the reality of his disease. Most alcoholics fight the reality for a long time.
It is important for you to understand the 3 Cs.
You didn't Cause it...You can't Cure it...and, you can't Control it....
You, also, can't help and support him through this....lol...and, he will probably ask you to do so. Any help that you offer...other than not being obstructive...will probably fall into the category of enabling......and, it will probably allow him to avoid the help of professionals and AA....which he seems to, already, be resisting.....
