OP, guide your wife through her workouts and encourage her etc, but keep your own workouts separate. It'll be too difficult to maintain your required intensity with all the distractions that she'll inevitably bring along.
Is it ok to rub one out between sets?

Hence my cardio suggestion
Send her to an aerobics class instead, if they still exist, or was that in the 80s?

send her to spin classes anyway
Or buy her a new vacuum cleaner
