Congrats on Day 6! Yes, my husband drinking was/is always a threat to my sobriety. In moments of weakness, alcohol was there, as was someone to drink with. I understand how hard it is.
One thing I have noticed about myself. . .when I find myself judging others, it is often because I am seeing my worst self in them. Meaning, I judge them because they trigger something about myself that I don't like. This in NO WAY excuses other's behavior. Just something I picked up on.
So go easy on yourself as you tread this path. And as others have said, you have no control over what he does. Take care of YOU as best you can in this circumstance.
