Romantic love only lasts 30 months, at best.
“…based on 5,000 interviews across 37 cultures and medical tests on couples, challenge the romantic ideal, suggesting instead that men and women are biologically and mentally predisposed to be "in love" for only 18-30 months. That is just long enough for a couple to meet, mate and produce a child.” [source]
After 2.5 years (24 + 6 months = 2.5 years), love hormones balance itself out. Bills, arguments, boredom, car pools and other issues will snuff out every surviving butterfly and afterglow. After 30 months from the first fall, people will outgrow romantic love.
This is all good news to me, you see? To know that the discomfort and inconvenience and the ups-and-downs of
the penis romance are tagged with an expiration date. To see a romantic fool’s head straightened!
One might argue, that some folks love longer than hormones. And I say, YES, while we all agree that it’s not
hormonal passionate love!
In fact, the most common justification to why people who do not love each other insist on staying together and endure children and boredom and mortgage is called marriage; a promise kept.
