That must have been a great shock and I admire your ability to understand that you have had a part to play in all of this, that you've been "checked out." Still, try and ride through the anxiety and don't be tempted to pick up a drink, 16 days is awesome (I'm on 16 too).
Only you can decide if you're able to talk about any of the the things that you are your husband need to discuss but I would suggest that if you are going to talk to him, you talk to him about the subject that you "own", your drinking and how you have stopped, and why.
Good luck and I hope you manage to work through these difficult times x
