Alcoholism

My husband and I have been together for 9 years, married for 2. We have a 2.5 year old daughter. 5 years ago, his dad passed away. He has always bottled that up and packed it away, thinking no one notices. Every now and then it surfaces, and then he goes right back to “hiding” it. He also has a high-stress job. Lately, his drinking has gotten quite a bit worse and I think there is probably a side order of depression. He knows damn well that it’s not a healthy coping mechanism. The problem is that he’s in denial that anything is wrong with him. He went to therapy for like 2 sessions and said it was stupid. I’ve asked him if we can do couples therapy and he has so far refused. I love him, and he is a beautiful soul. He’s an amazing father and husband, and I don’t want him to hurt anymore. Sadly, I’m at the point where I can no longer stand by and let it happen. He’s making poor decisions from the alcohol. My dad was an alcoholic, and I am not going to allow myself to be in that situation again. So, my question is: has anyone here SUCCESSFULLY navigated a situation involving alcoholism and managed to save their marriage?
