Moving on is never easy. It always be hard not to let go from it.
But the number one step on how to move on is.. "Learn to let go."
Learn to shut down every memories from the past.
You have no choice but to breath and not think about it. Because it is in the past now.
Past has always been a past. We can't change the past. It's not your future.
Different meaning, different words. So leave it behind.
Just move on.
Time will heal you so just let it go and leave.
Breath and smile.
God is working on your future.
