...are 2 diferent things.
Is it like that? I don't know.
What is definition of love?
What is definition of marriage?
Why do people married?
Is it because love?
Is it needed love to get married?
Maybe yes, maybe no.
Some people married with what-they-called love
some still remain
but in many case, they ended up by divorce
Some others married without love
through different scenarios
some of them getting love each other in the end
and they live happily
they made a deal with the bride
to complete their whatever-they-need
they happen to be an ordinary family
daily, boring, flowless activity
having a child, continue their lives
remain their ordinary life.
is it the purpose of marriage?
I don't know...
