Hon, you're not making him do anything. If we could make other people do what we wanted them to, this forum wouldn't exist. Besides, choosing between his family and a drink with friends now and again should be a no-brainer, shouldn't it? For people without a drinking problem, it is! But that isn't the choice, really, is it? Because that occasional drink leads to more occasional drinks, to more "special occasions", etc., etc., then he's drinking at home "now and then", what difference does it really makes, until it all picks up again right where it left off.
You have the right to live the kind of life you want to live, and you never have to feel bad about it. You have the right to raise your kids the way you feel they should be raised, and you never have to feel bad about it.
