Like a shark.

A relationship, I think, is like a shark. You know? It has to constantly move forward or it dies. And I think what we got on our hands is a dead shark. -Woody Allen, Annie Hall, 1977

Annie, there's a big lobster...

Annie, there's a big lobster behind the refrigerator. I can't get it out. This thing's heavy. Maybe if I put a little dish of butter sauce here with a nutcracker, it will run out the other side.
-Woody Allen, Annie Hall, 1977

And it's all over much too quickly...

There's an old joke - um... two elderly women are at a Catskill mountain resort, and one of 'em says, "Boy, the food at this place is really terrible." The other one says, "Yeah, I know; and such small portions." Well, that's essentially how I feel about life - full of loneliness, and misery, and suffering, and unhappiness, and it's all over much too quickly. The... the other important joke, for me, is one that's usually attributed to Groucho Marx; but, I think it appears originally in Freud's "Wit and Its Relation to the Unconscious," and it goes like this - I'm paraphrasing - um, "I would never want to belong to any club that would have someone like me for a member." That's the key joke of my adult life, in terms of my relationships with women.

-Woody Allen, Annie Hall, 1977

All broken hearts are circumstantial.

…all broken hearts are circumstantial. Every lovelorn jerk is the victim of bad timing, good intentions and someone else’s poor decision making.
Joshua Ferris, Then We Came to the End, 226

It was the only secret I kept from her...

In the entire history of our marriage, it was the only secret I kept from her, and eventually it became impossible to fix. With a secret like that, at some point the secret itself becomes irrelevant. The fact that you kept it does not.

I want her to melt into me...

Afterward, she lies nestled against me, her hair tickling my face. I stroke her lightly, memorizing her body. I want her to melt into me, like butter on toast. I want to absorb her and walk around for the rest of my days with her encased in my skin.
I want.
I lie motionless, savoring the feeling of her body against mine. I’m afraid to breathe in case I break the spell.
-Sara Gruen, Water for Elephants, 273

There are times I'd give anything...

Although there are times I’d give anything to have her back, I’m glad she went first. Losing her was like being cleft down the middle. It was the moment it all ended for me, and I wouldn’t have wanted her to go through that. Being the survivor stinks.
-Sara Gruen, Water for Elephants, 13
