Rosaline

"Here's much to do with hate, but more with love.
Why, then, O brawling love! O loving hate!
O any thing, of nothing first create!
O heavy lightness! serious vanity!
Mis-shapen chaos of well-seeming forms!
Feather of lead, bright smoke, cold fire, sick health!
Still-waking sleep, that is not what it is!
This love feel I, that feel no love in this.
Dost thou not laugh?" - Act I Scene I (Romeo & Juliet)

Romeo was in love, not with Juliet, but with Rosaline, his unrequited love.

At the first time, Romeo saw Rosaline as "The all-seeing sun / ne'er saw her match since first the world begun." but soon after she was replaced by "Did my heart love 'til now? Forswear it, sight / For I ne'er saw true beauty 'til this night." Romeo's love for her was short. She was forgotten. Romeo forgot Rosaline just as fast and as easy as he fell in love for Juliet.

Just after one second, Juliet became the dove and Rosaline turned into one of the crows and her name is only appeared in the later petrachan sonnets only to be compared to Juliet. Romeo was like an animist who is awed by the bright light of sun and turned his back after worshiping the moon in the night.

As the forgotten, Rosaline just sat in the dark side of Romeo's heart with her faint soft glow, just like the moon. Was she sad when she was forgotten? Did she regret being forgotten? Did she know she was forgotten? Did she really become "the pale and envious moon" killed by the "fair sun"? She was no longer the rose, because "a rose by any other name would smell as sweet", even if the rose was named Juliet.

Maybe she was indeed lucky that she remained chaste and profoundly proud. At least she wasn't a foolish lover or didn't die in a dim manner or wasn't a part of tangled stupidity. She was lucky, because she avoided love and she ran away from it.. Maybe she was lucky to be forgotten...
