You let go and allow the creator to do the rest. God sends people into our lives for a reason, season or a lifetime. It is our responsibility to distinguish the difference.
Sometimes we just have to accept and know it has nothing to do with you.
Letting go and walking away is one of the hardest things to do especially if the strings of your heart are still attached.
It may hurt for what seems like an eternity, but without you knowing it a new person will appear in your life who turns out to be your destiny. ~ Meredyth Beattie
Cover off the old story and starting the new chapter because everyday is a new chapter again.
Holding on to the unchangeable past 
Grudges are a waste of perfect happiness 
Let go of past resentment 
It’s better to walk alone
