Elvis Presley - Can't Help Falling in Love Lyrics Meaning

Wise men say only fools rush in
But I can't help falling in love with you
//This is the part where there is someone who is opposed and do not want their love to continue
but its too late to stop it since he already fell in love

Shall I stay?
Would it be a sin?
If I can't help falling in love with you?
//In this part he already lost his logic he does not know the right from the wrong.He is already consumed by his emotions.

Like a river flows surely to the sea
Darling so it goes
Some things are meant to be
//Everything now is up to their fate.
Let their destiny decide everything.

Take my hand, take my whole life too
For I can't help falling in love with you
//Ill be with you.. I will leave the life that I am used to.You are my life now.
