Why we fall inlove ?

Why we fall in love? Simple question but expands a thousand answers but for me being in love is the feeling that you can't resist though,you tend to feel loved and cared by whoever .

You know if you are in love if you can't sleep at night thinking him/her dreaming someone and feeling inspired all day long .You wanted to see him/her you're eager to meet him/her you wanted to spend most of your time with your loved ones .

In order to fall in love ,the two individuals need to be similar to a certain things like their favorite foods or anything that they loved to do .Similarity of two individuals can lead to a relationship that will bind them together as couples. Their personalities will complete each others,a need for similar interests,ideas and values remains important.
