(1) Challenge her on this addiction business, she is playing a tired old FALSE tape in her mind. One can certainly stop using antidepressants, though it is advisable to taper off of them. Once one becomes an alcoholic, stopping is much more difficult than that.
(2) Her answer is a cop out. Push more, -- "I agree that it is scary to try something new. But what difference do you think it would make to how you feel, to your health, to your children, to your functioning -- how do you think using alcohol versus using antidepressants to cope would affect YOUR LIFE?"
BTW, at some point you need to get back to figuring out what YOUR boundary is on this.... Personally, I would not stay with someone who would not try to get help for a debilitating condition that hurt me and my children and chose instead to engage in selfish, destructive behavior to avoid the pain.
