When hearts gone cold..

What do you do when hearts have gone cold?
Do you hang on?
Do you let go?
Do you long for the past?
Can you look towards the future?

What happens when YOUR heart has gone cold?
Do you move on and go with what your new heart says?
Or do you stick with the familiar?
And keep the promise you made at the altar?

What is right?
What is wrong?
What is the in-between?
Can life just be grey and still be great?
