"Love lasts 3 years" isn't just a french book by Frédéric Beigbeder. It's also a biochemical theory. According to Dr. Helen Fisher, LOVE can be broken down into three categories, each category is characterized by its own set of hormones stemming from the brain (Table 1).

This is the biochemical aspect. But the real question is: How long does love last?  We know that over time pleasure hormones diminish. How can we be with the same person knowing that physiologically passion hormones end up losing their intensity?

How many people do we need: one husband and one boyfriend ? 

Maybe yes maybe not.

Maybe if we make conscious efforts to go out of our routine, if we try adding some creativity to our relationship and remember the desire of being together.. one person can be your person, he can be at the same time your husband AND your boyfriend. You can make it work. 

One simple practical idea for tired couples: 

Leave the kids with a babysitter, book a hotel room in your own city and order a glass of champagne ! I promise this is the secret and I promise miracles will happen.
