Re: The science of love and why people fall out of it
That's a nice little summary. The time frame given for the initial love phase (2 to 3 years) is the reason I always recommend that you do not decide to marry - or actually marry - until the relationship has lasted 3 years or more.
There is also an exception to the statement: "the human brain is programmed to love one person at a time" so you must fall out of love before falling in love with someone else. Some people can love more than one person at a time, or have transitioned to long-term mature love and add a new love to the mix (who can eventually also become a long-term mature love as well).
Love is an ideal thing; marriage is a real thing; a confusion of the real with the ideal never goes unpunished. - Johann Wolfgang von Goethe
CELIBACY IS NOT HEREDITARY.
