He sounds like he is in the best place to help him to heal. So go back to the beginning:
"To kill the pain. Aside from two days when I had to work and go into the office I’m home starting to drink from the afternoon thru late in the night for the last five nights straight."
I would suggest that you both have issues that need resolving separately. It is detrimental to his recovery to be around someone who is using alcohol to "kill their pain" whatever and wherever that pain comes from. Focus on getting sober, your recovery. Am AA meeting would be a great start so you can start to unpick all this. All the best
