I have given all my love to him

"I have given all my love to him, but what do I get in return?
A broken heart; He broke my heart in two.
How do I mend a broken heart?
My entire world has fallen apart.
Sometimes I wonder how he do it.
He say things to me, about me, or behind me.
I gave him all the trust, but he misused it.
I gave him my life and he killed me day by day.
I want to loose my memory so I no longer think of him.
I want to sleep but my dreams haunt me with him in them.
I try not to weep but I can't stop the tears.
I can't seem to find a way out. What do I do?"
