Oh, I love that one... 'Isn't it just a matter of drinking less?'. Oh, it seems so logical now, why did I never consider that before!
It sounds like your hubby doesn't really get it... why not take him to an AA meeting or suggest he check out Al-anon. Obviously it is wise not to let your sobriety dependent on him 'getting it' but it would help if he wasn't offering you booze x
