Any SF series featuring successful couples?

Most of the popular SF action/adventure series seem to focus on a
single protagonist: Miles Vorkosigan, Lucky Starr, Honor Harrington,
Kris Longknife, Bill the Galactic Hero, Dr. Peter Conway, and so
forth.  Rarely do these characters suffer the distraction of love and
affection.

Are there any SF series (popularity not necessarily a criteria, but
I'd like something with marketability) which features a married
protagonist, one whose spouse plays a regular and major sup****ting
role throughout the series?  (Diplomatic Immunity does not count as "a
series.")
