Romantic love is an addiction.

You don't come home from the office to spend time with another job. Hopefully you come home to someone you can have a good time with.

Falling in love was not really a choice; it just struck me.

In general, men are wired to notice obvious signs that convey interest in mating - a warm smile, for example - and ignore other subtleties, like if your lipstick is faded.

There exists no culture in which adultery is unknown, no cultural device or code that extinguishes philandering.

Romantic love allows you to focus mating energy. Attachment sustains that relationship as long as necessary to raise your baby.

The brain was not built to walk into a bar, where you know nobody, and start a conversation. That's not the way humanity has courted.
