Crush vs love

"Opposites attract" well this a well proven fact of physics.It is said science is a way of life and this maxim gains its importance when we ourselves become catalyst for the reaction of opposite attraction.But there's another countersatement to back it"opposites attract but likes endure"...
So finally after enough beatin around the bush let me come to the topic.
Crushes are merely teenage blues or may be younger than that(keeping in mind the latest trends) .To be more rational, lets not consider age as the barrier.
A crush is a "strong liking for an individual".I guess every individual sometime in his/her own life experiences this feeling.For its purely a natural process....you were never taught anything about it,You never plan it,You neither wanted it but it just happens.
For some it may be for a moment like a bubble which bursts out,For some it may be a long phase which withers & dies.
Crushes are merely infatuations, nurtered by laws of attraction.It transcends logic & reason.
One can never comprehend why suddenly you are attracted to someone.It may begin because of a beautiful face,a sweet voice, a handsome body,a charming personality,a sparkling smile, a kind jesture or nothing at all.
It may be standing at the window as he reluctantly drives away, it maybe waiting for her call,
it may mean lazy dreams of future with him/her ,it may be the restlessness to meet,it may be the urge to dress up to impress,it may be blushing away to glory when he complements,it may be the way she looked at you through the corner of her eye,it may be an act of bravery..................it may be anything but love.
And this is perhaps the reason why crushes crash & do not last.
For true love is an understanding which compels u to be together with someone to make up for the mutual deficiencies (as we all are somewhere imperfect....).it is about trust,its about knowing each other for what they are and not expecting to change like two halves of whole ,complementing each other.Its a process which can be understood only by experiencing it..............(some experience it b4 marraige n sum aftr)
