It is possible to not do anything that hurts your spouse without sacrificing what you want, if what you want is a happy, mutually satisfying, compatible marriage. Above anything else: opposite sex friendships, eating out, material possessions, trips, etc.

IF you want those things ABOVE wanting a good marriage, then I can see why someone would think they were sacrificing.

Marriage is the triumph of imagination over intelligence. Second marriage is the triumph of hope over experience.
(Oscar Wilde)
