Coming to the facts
This is what I am
This is where I live
I can't build you a castle
I can't afford a diamond ring

I have to work for my daily food
I have to walk miles and miles everyday

My life is different from you

Being with me or
Living with me

Is not a right decision

Loving a person is making sure that they are happy

You will be happy leaving me and taking diversion from my path

Hope you will understand it.

I am helpless in this case
I can only make you happy by leaving you
Have a good day and good bye
