One is enough

From last few days I was thinking over this topic.
All of us in reality or in dream wished for lover other than whom we married.
Is one is not enough.
Can a boy and girl ever be just friends, be a good friend , but then same question again arises can a boy and girl be just friend without any chemistry working between them.
It is very difficult to answer, like a complex simplicity.
Actually everybody crave for a friend who can listen to all silly things one like to share, in between praise a little, and can be ready for dinners, movies etc.
But keeping out the physical attraction, but it is possible hmmmmmmm.
Everybody wants someone in life who makes you feel like you are miss world or you are the only one best one left on this planet Earth.
At the first sign of boredom pulls you to go for an relationship and then out of disillusioned and restless nature slowly friendship turns into physical relationship, its then become really dangerous, so it’s better at the first sign of boredom, or when you seem disillusioned and restless control.
Because then it is called bigamy, polygamy etc.
Although hhistorically, polygamy has been practiced in many tribes; it was there in society from long time. And still it is practiced.
Medically we can have many answers but truth is we always wish or dream of super woman or superman, which can be flawless and a perfect.
