OH, Flavia.....I appreciate how hard it is to say no. I have had to do it!!
In the bigger picture, you did the right thing.
No alcoholic benefits when anyone offers them a soft (softer) cushion for the natural consequences of their drinking......
In my opinion, your refusal to rescue him is actually an expression of caring ...as well as your own self-care.
Good for you in doing the hard thing.....
