The pain will go away with time. For some reason you weren't right for each other and thus this chapter of your lives has closed. You are just adjusting to this change. Once change is complete the pain will go and you will be ready for a much better relationship than the one you had.
Don't cry, don't regret and don't blame
Weak find the whip, willing find freedom
Towards the sun, carry your name
In warm hands you are given
Ask the wind for the way
Uncertainty's gone, your path will unravel
Accept all as it is and do not blame
God or the Devil
