If your wife wants you to travel with her, go regardless of the personal cost to you.
My wife had to go to a 4 day class in Texas, and even though I had a fantasy football draft, work, school, and plans to hang out with friends, I cancelled them (or rearranged them) to be able to go on the trip with my wife.
This paid huge dividends into the good husband box. Not only did I get to call most of the shots for the whole trip, I got to spend an amazing stress free weekend with my wife, and I got other benefits as well.
Yes it was a sacrifice, but in the end the greatest sacrifices reap the greatest rewards
