Hi Doug. I don't see anything wrong with pointing out all the hidden empties as long as it's done in a way to show your concern and love for her rather than anger or shame. Like what are you doing honey? You deserve more than this. I love you and I'm worried about you.
At the end of the day though she has to want it herself, but there's nothing wrong with helping her to see that some part of her does want it. No one wants to be hiding bottles around the house out of secrecy and shame. If she was really ok with it she wouldn't be hiding it.
