What happens to love when it's never realized?

When a love between two people is left unspoken?

Does it die over time? Is it replaced by a newer love, or does it sit, untouched in the back of our minds, waiting for the opportunity to resurface?

If you haven't been able to be with someone in your life who you've loved, what did you make of that love?

I'm really intrigued by the question of where love goes when it isn't realized and what we do to try to hide, express, destroy, or cultivate an emotion that ultimately can't be controlled.
