It ain’t no picnic for me either. Sometimes I think the belief has me, rather than vice versa.
Lust is easy to cast aside for feelings of love.
When I hold the love of my life in my arms… I cannot express the feelings of peace with words.
Love is a horrific illusion that wants to stab you in the face. DON’T LET IT!
(bitter, party of one.)
Simpsons quote. Homer to the van Houtens.
Stupid Rhymer, you left out a form of psychosis. That doesn’t necessarily make it bad, and it’s other things as well, but it’s most assuredly that.
…never having to say you’re sorry.
Bonus points to those who can name the two movies this is from. 
Ryan O’neil (sp) in Love Story and RO replies to Streisand saying it something like, “That’s the most stupid thing I’ve ever heard in my life” in another film.
It’s “Stoopid Rhymer!”, not “Stupid Rhymer,” my friend.
Love is like a hurricane; it happens in Florida and it ruins everything.
Why, yes. Three times. 
This last one has been successful, because we’ve figured out how to do that - ‘extend one’s self for the purpose of nuturing another’. You have to have trust in each other for it to work; and you both have to be as consistent as you can be with the nurturing. You have to be able to let your guard down and let the relationship just ‘be’. It’s indescribably delicious.
So’s an Almond Joy, and I’ve been through more than three. 
#2, hands down.
I prefer this wording, however:
“Love is that condition in which the happiness of another person is essential to your own” (Robert A. Heinlein)
.
And they say romance is dead. {Sighs romantically}
taking the beer cans out of the back of your truck before you take her to the drive in.
That phrasing is not identical in meaning to what I wrote, though. If happiness were the only criterion, then I would not object if someone I loved became addicted to heroin, so long as the drug were making her happy. Also, loving someone can lead one to commit actions which bring the actor peace rather than happiness. For instance, I was once in love with a woman but came to realize that she was truly better off without me. There was a point during the dissolution the relationship in which it seemed very likely that she would choose to remain with me, even though she knew she should not. That would have made me happy, but I could not have been at peace.
(I hope that doesn’t sound self-aggrandizing. I don’t mean that I was being all that self-sacrificing; rather, I mean that there were things I valued more than my own happiness and I acted to obtain what I valued.)
I guess, sometimes you feel like a nut. Sometimes you don’t.
Love is the state in which the well-being of another person is essential to one’s peace of mind.
“Love is what you’ve been through with someone.” ~James Thurber
“Love is absolute loyalty. People fade, looks fade, but loyalty never fades. You can depend so much on certain people, you can set your watch by them. And that’s love, even if it doesn’t seem very exciting.” ~Sylvester Stallone
“Love consists in this, that two solitudes protect and touch and greet each other.” ~Rainer Maria Rilke
“Love is the silent saying and saying of a single name.” ~Mignon McLaughlin, *The Neurotic’s Notebook *
“Love is staying up all night with a sick child – or a healthy adult.” ~Sir David Paradine Frost
“Love is voluntary insanity, infernal paradise, and celestial hell – in short, harmony of opposite yearnings, sorrowful laughter, soft diamond.” ~Umberto Eco
“To love a thing means wanting it to live.” ~Confucius
“You know you love someone when you feel their pain and joy as powerfully as your own.” ~Ann Brashares
Point taken. But to me it’s unnecessary. I’m not saying “I’m happy if she’s happy”, but rather “If she isn’t happy, I can’t be either.”
ANYWAY, I still think #2 is the correct choice on your list.

Love does no consist in gazing at each other but in looking outward together in the same direction.
The Little Prince said it best.
