Understanding the special paint and brush poem

The girl is your special paint and brush.
She would heal your wounds in a rush.
She will bring you up never down.
she make you smile breaking the frown.
She is there for you when you drown.

If you abuse the power she willv leave you.
You will let another man live the life you once had
your is heart full of jealously,
with your eyes of envy
and mind recalling precious memories

your forced to watch the life that made you glad.
you Lost the world you once had.
Your only hope is she forgive you
and take you back.
your heart beats full of strife.

you truly wish you could die.
but you can't because your hope keeps you alive.
just one more chance keeps the heart beating.
but a wound becomes infected without bleeding.
like you without inspiration
you barely keep breathing.

This is the curse thats left with you.
All because of a special paint and brush
