Why is it you?

Why is it you that i can tell everything to?
Why does it have to be you that shuts me out of your life?
I no u no I feel like shit when you do things like that.
It sucks cause we're not even friends anymore.
You used to say I was your best friend.
Your one and only.
Now i can't believe it, a new year has started and ive moved on.
Im guessing you have to.
But I want you to no.
That you will always be the first one i have to choose.
