Nah, love can be extinguished fairly easily and fairly quickly.
Obviously the longer you have been in love with someone the longer it takes for the love to just disappear, but even people who have been together for over twenty years can fall out of love pretty quickly if one spouse finds the other spouse cheating on them.
The stronger the connection, usually the more painful falling out of love is, but love is both incredibly strong and incredibly fragile at the same time. But honestly I think this makes people appreciate love even more.
That being said, there are plenty of people who go on loving someone even after that person has treated them like absolute crap, including cheating on them. But that can be social conditioning as much as anything else, such as if you had an abusive parent or some kind of other emotional problems.
Of course this is all under the assumption that humans are naturally monogamous, which is quite an assumption. But based on our biology (nine month gestation period and having to take care of children for a very long time before they are self-sufficient), there is a fairly strong argument that monogamy or something close to it is at least potentially normal for humans.
We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls. The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke
It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...." Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S. Thompson
