Make sure your partner understands the need for "me-time"...
Usually requires them working a 8-5 job and understanding that when you get home, you sometimes just need to relax without having to give further attention to the spouse.
My wife understands completely, my time usually involves mountain biking twice on weekends and many a night playing PC games. However I do try balance is out, and when I game its only for a couple or hours and not the whole night.
She loves to read and watch crap TV shows.. she can do this when im doing my thing, and we are both happier for it.
