Can't Be Replaced

Even though I'm all the way out here,
It does not mean I'm not near,
I will always be in your heart,
There is nothing that can tear us apart,
Because my love for you is true,
And there is nothing that anybody can do,
When you need me i will always be there,
That is how much i care,
And if i am your one and only,
Then nobody or anybody can replace me
