Not sure what to do, my wife said she likes it when I have a couple of drinks
I'm not sure I quite believe that. You have posted before about your wife's concerns about your drinking. Now all of a sudden, while you are struggling at day 3, she wants you to drink?
Were you being sulky in the hope that she'd accept your drinking as the least of two evils?
You've been pretty secretive about your drinking, drinking before she gets home with your child. Maybe it's time to disclose the extent of your problem.
The drinking problem is yours. The recovery is yours too. Take ownership of it. Don't drink tonight. And try to be pleasant.
