In a marriage, or any relationship between two people, there is a need to maintain a certain sparkle.
Reason? It differs with each couple. However, the basis of it all is to feel something new, or a reprise of a familiar feeling.
Upon watching "Sex and the City 2", Big and Carrie discusses the idea of spending two days a week away from each other, to regain and maintain the "sparkle".
Some couples dread spending all their time, doing everything, with each other.
They dread growing into a certain pattern, day in and day out.
Hence the need to go out on "dates", like "the good old days", pre-children and other adult-like commitments.
Every couple has their own kind of marriage, their own norms and rules.
Some like to go on "date nights", just the two of them (life after kids).
Some like to stay home.
Us, we like to curl up in bed after our son is asleep and watch Dexter or Criminal Minds or The Vampire Diaries or 30 Rock or Chuck or Glee and we'd silently squeal or cry or laugh, all the time together.
Or
If it's on nights when Husband needs to work on his paper, I'd just read something Neil Gaiman, all the time together.
Because we like being together all the time. No point in making a face and saying,
"Eee, tak boring/rimas/lemas ke?"Everyone has their own kind of marriage/relationship.
And it's all for the sparkle.
