Not sure what method you are using (if any) and whether or not you have a plan but it might not be a bad idea to make a plan.
Maybe schedule some special project while your wife is away to keep you busy.
Stick close to SR
Be ready for your AV to start its nonsense and nip it right in the bud by stating:
I don't drink no matter what.
If you do support groups like SMART, Refuge Recovery etc, maybe plan to attend a few meetings.
You could also plan to do some volunteer work. It will not only take your mind of your problems etc. but you will also get to meet some really cool people.
Anyway those are just a few thoughts and suggestions.
Remember, you are an adult and your sobriety should not be contingent upon someone else being around or not.
You made a good and healthy decision to quit and there is no reason why you should not stick to it!
You can do it!!!
