If your wife is stressed what about if you book a day at the spa for the both of you a day of pampering & then go for dinner that evening make a romantic weekend of it and just try to listen if she does say anything im not saying you dont btw sometimes with my gf of 15 yrs i just tell her get it off your chest and i will listen to her work stress il listen untill she feels better sometimes i throw in a foot massage or a backrub that sort of thing
Best wishes Scylla
