Old best friends for life

We used to be best friends, and i thought you loved me just as much as i love you.
But i was wrong, you filled me with lies, and i believed you.

I thought you were the most perfect friend i could ever get.
But no one is perfect, i know that but it doesn't seem like you know that.

Sometimes i feel like you expect way too much of me.
Its hard to live up to, every day.
Maybe we just weren't meant to be best friends for life.
