Hello John, and Welcome!
One day at a time is sometimes all we can do...
I'm sorry about your wife and hope that she will one-day choose recovery and hold onto it with everything she has. It certainly doesn't sound as though she is at that point yet, though.
I'm glad you have reached out. You deserve to some peace and joy in your life, and SR is a great place to start! You will find a lot of support here and the combined wisdom of people who are in various stages of the same life situation.
Please make yourself at home!
