You don't know what you got till it's gone

Why do I feel like this?
I try my best to forget about you,
Forget about the things you have put me through.
You made me feel that I did not exist,
Did my feelings ever mattered to you?
Were your feelings real at all?
You said you cared and loved me,
But, you kept secrets from me,
Lied each day to my face.
We were a mistake,
I think I need my space.
You took me for granted,
You were the one I wanted.
I thought you wanted me,
I thought you needed me,
But, I guess I was wrong.
Your addiction is far too strong.
You don't know what you got till it's gone.
