I would also like to express my opinions on the phrase "love can be nurtured".

Love can grow stronger.

Infatuation hardly turns into love.

Because the basis of the two...

Are different.

Infatuation...when you only 'want' the person...or something to that extent...

When you start something with such selfish emotions...

Love is patient, love is kind.
It does not envy, it does not boast, it is not proud.
It is not rude, it is not self seeking.
It keeps no record of wrongs.

Love does not delight in evil but rejoices with the truth.

It always protects.
Always hopes.
Always trusts.

Always perseveres.

That, is the bible definition of love.
Add in that humans are not perfect, and are bound to fail from time to time.

And I think I do love you.
