I am separated from my husband due to his alcoholism and abusive tendoncies because of his depression. I know what it means to be in love and hoping that you're better half will get on the right track to make themselves happy. From my personal experience I would suggest to you to attempt to push him towards continued help; but he can only get help if he really wants it. Working ones way through depression is difficult and takes tons of work; it's not an easy road but he has to be willing to put his best foot forward and not give up on himself. Progress a day at a time is you're only hope for a genuinely happy partnership and healthier life together and as individuals. Best of luck!
