We all know lust and infatuation period doesn't last forever.

Humans aren't monogamous .

So why is the ideal marriage lifelong monogamy?

Lifelong partnership sounds great but why can't you see other people as well.

20 years into your relationship ....kids are out of house.

Why not allow flings with other people?...experience acting on lust again

Married people wouldn't feel the need to cheat because they could tell their partner they have a crush on someone.

Lifelong monogamy just seems silly ...depriving yourself of lust because it's the right thing to do...it's an ideal that most people will fail to hold up

Why doesn't the ideal relationship include getting some strange?

Will the ideal relationship change to a lifelong partnership with no expectation of monogamy?
