Liar!!!

Didn't lie to me?
You didn't tell me when
My best friend
Was in the hospital after
He asked you to let me know,
And when I found out from him,
I asked you about it, you simply
'Forgot to tell me'.
How does one forget to mention something
That big???!!!!
You didn't let him know I
Was in serious trouble
With my abusive cousin
When I asked you to tell him,
You didn't, you simply 'forgot'
About that too!
You didn't lie once or twice,
You lied so many times that you lost my
Trust, something you'll NEVER
Get back. You didn't lie to
Protect me,
You lied, and that hurt me.
I hate liars,
I hate being lied too,
Because that means I'm not worth the
Truth no matter how bad the truth may be.
You've lied to others about me..
To the people I care about.
I'm quite displeased with your
Actions, and disappointed.
You asked how you lied to me,
Heres part of your answer.
