Ok, wife, husband, girlfriend, boyfriend, or whoever. Have you thought about discussing with them what they should do if you are together and a situation exists which becomes dangerous enough that you are forced to draw your weapon? How they react if you do may make the difference in the outcome.
In other words, are they going to react in a way which may create such a distraction for you that you don't react or respond properly to the situation? Will they be trying to influence or control what you do during the situation? The way I look at it is if I am the party who has perceived the threat to be real and have drawn, I am in charge and I would not want my wife voicing her second guessing of the situation or doing something like yelling at me with the intent of making me take another course of action. Such a distraction could easily result in one of us or both ending up dead. I think it's something like the backseat driving spouse (not saying my wife is that, but you get the point, I hope). Such can cause an accident if it results in driver confusion.
The situation which prompted this scenario question was an instance I read about not long ago. A convenience store clerk and his girlfriend (guess she was working with him) experienced an armed robber who apparently had deadly intent enter and proceed to attempt to rob the store. The clerk was a CHL and as he was drawing his weapon his girlfriend went into a panic and screamed at him something like "don't do it!" Basically trying to stop him from drawing on the BG. Fortunately he was able to tune out her distraction and shot and killed the BG but if he had allowed himself to be distracted, it could have ended differently.
That got me to thinking that I really have never had that discussion with my wife. She's not exactly the backseat driver sort, but she has, too often, being the strong personality she is (I love her in spite of it ) second guessed me in situations (thankfully so far, not life and death situations) and those can result in hesitation from intended courses of action.
Likewise, what have they been taught to do as for as their own movement? Grab and cling to you? Hide directly behind you in the possible line of fire from the BG? React in a way which draws the BG attention to them possibly getting them shot?
What do you think?
