If dh EVER did that I would kick him out, end of, but, as you said your circumstances are difficult with him being the sole owner of your house.
I think in the society that we live in, it is becoming more and more common practice to have alcohol served at childrens parties.
I've just come back from a 5yr olds party where alcohol was being served, I've had one glass of rose and now come home and settled down with a cuppa.
Not generalising men in particular but, my dh also has an inability to stop at just one or two.
