This was always tough for me...my exA used to hide bottles all over the house.
After he left I found them in the most strange places, I guess he got so drunk he
even forgot where he put them. I never took long for me to figure out if he was
driniking or not, passing out and peeing one's self is a dead give away.
I'd say let it go, you already know he is drinking at least 3 days a week, tough feat for an A, if he could control it like that, he wouldn't be an A..... IMHO
Love, Patty
