Studies conducted in the US, showed that half of the couples taken as a case study ended up in separation due to unrealistic expectations they had towards each other. 

These misperceptions increase due to the active work done by hormones at the beginning of the bond or as it is otherwise called, the period of chemistry. This stage can blind people a bit and only when the chemistry fades or disappears, they realize that the partner was not as ideal as they thought it was. Why does this happen?

During this study, experts asked more than 300 people what the word chemistry meant to them. After the answers, it turned out that 9% of women and men associated this period with the word "love" while others with "biological reaction" or "common desires".

In fact love goes through 3 main stages; lust, attraction and devotion. The first stage, commonly referred to as "chemistry", is nothing more than the work of estrogen and androgen, (female and male hormones based on their biological function to reproduce).

When these hormones move from the climactic to the quiescent phase, couples can better understand how they feel about each other. Things may not look as good as they used to, and his behavior may not seem so interesting.

Of course, passion can keep you awake for very long, even after the period of fiery chemistry is over. Talk to each other as in the first meeting, hold hands more often and commit to your partner. So simple!
