Jason I hope you can make that meeting and more, I will say this and let it lie, a secret is a very bad thing that weighs heavy upon one, especially one kept from your spouse.
Do you think your wife would be mad at you if you told her you were going to an AA meeting to help you stay sober?
I can tell you that my wife was damn happy when I went into detox and then was going to at least one meeting a day, even then she was still ready to leave me with the kids for some time after I got sober.
