Hunnie why?

I don't know what to do,
I don't know who to trust.
I thought I could trust you,
But it seems our friendship is starting to rust.

You betrayed me once,
And I forgave.
I feel like a dunce,
Because I thought our friendship was saved.

But here we are again,
The same predicament as before,
You keep saying your my friend,
But you act like it's a chore.

You take what is important to me,
Right out from in my hands,
I can't believe I was too blind to see,
In my heart your knife lands.
