What happens when out of two best friends, one fall in love and other is not?

What happens when you can't live with it and can't even leave.

What happens when one is expressive as hell and other can't even say a word?

What happens when there is no choice but to suffer?

What happens when one is serious as hell and other is not?

You know how they say love is a beautiful feeling and it is always good to be loved by other. And it's great when the one you love, loves you back. It's the feeling of great pleasure, heaven on earth, butterflies in stomach, the happiness which can be seen through eyes only. But what happens when it's one sided? 

One sided relationship is a relationship in itself. You don't need anyone to be with you, you don't need someone to give validation, you maintain that relationship with you. You just love the idea of being with them in your imagination and everything that can connect you with them. They are all over in your head, hopes and prayer. It's silly for others that how you keep seeing them, thinking about them, thinking of your future together with them but that means the world to you. 

But let's talk about the other side. 

Loving someone or thinking about someone from far away is one thing and when your best friend falls in love and you know about it and you can not do anything about it because you don't feel the same way is another thing.

Now talking about ups and downs in a friendship is really really a distress. You can not decide whether it will work being friends or not. You can not really hold on to it and can't even leave it that way. So, this lead to a suffering where you can stay and and hurt or leave and time will heal, either way you will be hurt.

In terms of being expressive, I think it doesn't work everytime being opposite to each other or I can say there must be a willing to accept each other in that way. In order to understand each other and maintain the relationship in such a way that  SILENCE DOESN'T BOTHER YOU. In my opinion STRONGEST RELATIONSHIP IS WHEN YOU CAN BE COMFORTABLE IN SILENCE. 

What I have understood from my experiences is that if you ever come to know about your best friend's feelings please either accept it or stop being in contact with them right away. I know it'll hurt but you can save yourself and them also from being suffered and from a long term sadness because it is going to happen so far so soon.
