What's the foundation of a relationship?

After going through what happened these days

I really and deeply think that the foundation of a relationship is "Trust"

Without believing each other, the relationship is just not solid enough 

I am so surprised and sad about how fragile a relationship can be

I used to want all or nothing 

but later on I found out that's just impossible, else I am just too selfish

So I started to realize that how important the word "trust" is 

If a relationship is based on having doubts on each other,

then we all know that it will definitely fail sooner or later

The most difficult part is how to draw the line

You don't want to hold them to tight so you choke them

But you don't want them to think you ignore them as well

That's why we have to believe in others

Because you trust them, you wont misunderstand them easily

As a result of that you wont fight or argue so often

That's how a strong relationship start to build

You might disagree with me and that is fine

But trust is the most important thing to me when it comes to relationship

- P.S.  You almost back down on everything that you have tried to make me believe when I am just about to...

Well done ...
And thanks to you, now it is much harder for me to trust anyone again
