Love story plots, or 13 ways to mess with your characters

One of the great appeals of fiction writing is getting to inflict your own fantasies (and miseries) on your characters. While we often don't have much control over our own affairs of the heart (as Valentine's day so poignantly reminds us), at least we can write a love story exactly the way we want.

In honor of/in derision of Valentine's Day, I looked over some famous love stories and grouped them into 13 ways to mess with your character's hearts:

1. Forbidden love: Romeo and Juliet, Lancelot and Guinevere, Paris and Helen, Anna Karenina, Casablanca, the Thornbirds, Twilight. I think perhaps the most archetypal and most-used love story plot.
2. Love triangle: these proliferate the YA scene today, led by Bella/Edward/Jacob and Katniss/Peeta/Gale, but they've been around a long time, such as in The Phantom of the Opera.
3. Secret love: where one person loves the other secretly, believing the object of his/her love is unattainable. Examples: Shiver (Sam loves Grace for years but she knows him only as a wolf), the Little Mermaid, Memoirs of a Geisha
4. One-sided love: similar to the secret love plot, except the besmitten one announces his/her love instead of keeping it secret. Beauty and the Beast, the Hunger Games (Peeta and Katniss)
5. Love forsaken: a pair of lovers where one rejects the other (usually because of unequal status or to honor the family), and then regrets it (Wuthering Heights, Persuasion)
6. You're the last person I'd ever love: two characters start out disliking each other, often quite intensely, and then fall in love as they get to know each other better. Pride and Prejudice (Elizabeth and Darcy), Stardust (Tristran and Yvaine), Shrek (sort of)
7. Happily-ever-after love: the classic fairytale love story, where lovers must overcome obstacles to be together. Examples: Westley and Buttercup (Princess Bride), Captain Navarre and Isabeau (LadyHawke)
8. Love torn apart: the opposite of a happily-ever after, where love reigns for a while, but then is torn apart by circumstances (The Time Traveler's Wife, Jane Eyre, Orpheus and Eurydice)
9. In love with the wrong person: the classic is Gone With the Wind, where Scarlett thinks she and Ashley are destined for each other, but she's really meant for Rhett. More recent example is the movie Enchanted.
10. Reluctant love: where two people are forced by circumstances into a betrothal or marriage. Sometimes both are reluctant partners; sometimes one is willing, the other reluctant. As the reluctant one comes to know her partner better, they genuinely fall in love. The great Bollywood love story Jodhaa Akbar. Outlander by Diana Galbadon. Love Comes Softly by Janette Oke. I know there are lots of others... anyone?
11. Discovering love in a strange place: Tarzan and Jane, Jake and Neytiri in Avatar, the pair in Stargate
12. Re-discovered love: two lovers have a falling-out, and but fate forces them to work together and they rediscover their love. Ed Harris and Mary Elizabeth Mastrantonio in the Abyss, Jeff Goldblum and Margaret Colin in Independance Day, Bruce Willis and Michelle Pfieffer in the Story of Us. Can anyone think of any novels with this sort of relationship?
13. Platonic love: Rose and Lissa in Vampire Academy; Frodo and Sam in Lord of the Rings; Thelma and Louise; Harry, Hermione and Ron in the Harry Potter series. Striking examples are often in a guardian/guarded relationship, master/protege relationship (Obi-Wan and Luke), parent/child or sibling relationship, hero/sidekick, human/animal pair (Calvin and Hobbes, the knight and the dragon in Dragonheart)

I thought I'd be able to pick out my favorite type of love mess, but I really can't. Do you have a favorite kind of love story? Did I miss any? And if you've read Across the Universe, what type of love story would you call Amy's and Elder's?
