Mitch I am so sorry you are going through this. My husband is an alcoholic, so i know only too well the frustration and anger you must be feeling. i urge you to go along to Al-Anon and get some support there. My husband has had cancer too and he drank alot of the time to cope. He has ended up hospitalized for mental health issues brought on by the drinking. You cannot stop him drinking, but you can learn to cope whether he is or not. I found that carrying on with my own life, plans etc was the best way forward for me, rather than his drinking taking up my every waking moment. At the groups you learn to take the focus off the drinker and put it back on yourself, the only person you can control. I hope you will find a way forward. I’ll be thinking of you.
