Helen Fisher: Studies of the brain in love - TED.

Quote
"
After studying the results over the years, Fisher has come up with a theory that love is created by three distinct brain systems — those for sex, romance, and attachment. She has described her findings in several books, most recently ‘Why Him? Why Her?’ Here, an oversimplified version:

…

The three systems are intertwined. For instance, sex boosts attachment. When you have an orgasm, your brain pumps out oxytocin, heightening feelings of closeness. Which is why one-night stands often last past one night.

A.J. Jacobs: How Do I Love Thee?

I’m interested in psychology in general and I was very interested in this topic a while ago, but it’s a a topic of renewed interest for me at the moment. I think the above part is particularly interesting: recently fucking someone boosts levels of happiness and attachment-inducing chemicals in your mind, making you think you are a perfect match and that you love them just long enough to start a relationship that may bear a child.
