I lot of people would now say, ahh, that's just infatuation/crush/etc, not love. But I hold that those feelings are part of it, though not the "deepest" part.
The brain is flooded in monamines (dopamine, norepinephrine... and serotonin plummets) in the "falling in love" stage. It makes us excited and happy, and associates those feelings with the person. (dopamine is also activated by cocaine). Sweaty palms, lack of concentration (ie, thinking of nothing else but the person), butterflies, etc, are all signs of this.
This is also where a lot of people fail to make the jump to the next stage, and instead have a series of short relationships to get to that chemical high.
We can't stay drugged up forever, so eventually that rush fades and hopefully there is a strong enough bond to keep the couple together. We get the hormones Oxytocin and Vasopressin instead. They basically.. encourage monogamy. This is where a couple is attached to each other, accept each others flaws, etc. As vashti says, love is what is left over after infatuation dies. I think the chemical rush part is also part of the love process, if you will, but this later stage is indeed the truest, most meaningful and long-lasting stage.
Oxytocin is released during child birth, helping to create a strong bond with the newborn. I bet anybody who's given birth should know how amazing it feels to hold the baby right afterwards.
Oxytocin is also released during orgasm, so yes.. sex keeps the bond going.
I know less about Vasopressin, except that there was an experiment with voles (who are monogamous, and interestingly, they have way more sex that is actually required for reproduction). It was found that the hormone is linked to life-long mating, and that when the voles were given something to suppress it, they lost their devotion and the male did not defend the female from other males.
