No wife, but a girlfriend of 3 constant, happy, and loving years..
Best to do, like already mentioned, is to get her involved. She loves helping me start the fires, trim the meat, season it, be an extra hand when trying to take off meat from the pit, slice up ribs when they are done, etc. About the only thing she doesn't do is help drink the Jim and Coke and clean up the ash!!
Plus it helps that she likes the results..
Sometimes she does let me know that I need to hold off on the "big time" BBQ for a little bit to keep it from getting old but she doesn't complain if one of the Webers get fired up to roast some corn, potatoes, kabobs, or the like on an almost nightly basis.
I think shes a keeper fellas!
