What you are feeling and expressing is entirely normal. You need to see that he gets a referral to a hepatologist. But you cannot stop him from drinking. He has to be the one to do that--to WANT to stop and then go about getting the help he needs to quit.
You need to decide if you are willing to put up with this behavior or have had enough and are ready to walk. As a sober alcoholic, for me it would be an easy decision. Life is too short to be unhappy.
And by the way, alcohol and antidepressants are a deadly combination. Also, since alcohol is a central nervous system depressant, it is canceling out any good the antidepressants might be doing. He may as well not take them.
