You never really loved me

You said you loved me
And i loved you
You said you understood me
You always knew everything
But you couldn't trust me
Even though i never gave you dout
You thought i would betray you
But i kept everything right
I never slipped a word of any thing
But you always needed to talk
You lied to me and tried to cover it up
By trying to pin some blame on me
I took it for way to long
Then it finally hit me
You never really loved me
Did u truly understand me at all?
