And yes, old love is not the same as new love, just as old comfortable shoes are not the same as new shoes. To stay married to the same person for one's whole adult life, you have to be willing to trade off the feeling of shiny, new love for comfortable, old love. It's not the same. But it has its good points. People who only want shiny, new love will never have comfortable, old love because they will keep throwing away their partners and searching for new ones. There are lots of people like that. You have to decide for yourself what you want.
