I think we've forgotten what romantic love means.
A romance in classical and medieval literature is, archetypically, a story that tells about how true love (true in the sense of faithful) overcomes obstacles for the sake of union with the other. At its core, a romance is an adventure.
Now, in life, there is no shortage of opportunities for adventure. What is lacking is individuals willing to embrace the risk, danger, and hardships associated with it.
Almost any marriage that has stood the test of years will have had its trials and adventures. With more people marrying late, or getting divorced, many have been denying themselves the opportunity for romance.
