Love with marriage is like dinner with peptobismol: only for those with a weak gut.
Commitment, a.k.a. blind denial of the perpetually changing nature of life, is the manipulative pseudovalue of choice for those that have become a burden but refuse to be left behind, such as an employer that has little to offer or a middle aged soccer mom with the appearance and sensuality of a minivan. In as much as it opposes the forces of the free market, "commitment" is decidedly anti-capitalistic and un-American, an unwelcome imposition on individual freedoms.
Marriage is a commercial transaction by which two people implicitly agree to certain rules of division of property at the end of the contract.
It is important not to confuse the three concepts. If marriage was about love, women would not oppose prenups. If love was about commitment, cheating wouldn't matter as far as you don't "commit" to your extramarital affairs. If a person thinks that the three things are inextricably tied together, said person has not grown enough of her own thoughts to be able to distinguish them from the "party line".
