Mythology is full of examples.
Orpheus lost his Eurydice because he turned to make sure she was following him out of Hades. Psyche lost Eros because she allows the distrust of others to break the covenants between them.

It's so hard, to choose to move forward. I've seen what living in the past can do to a person. It can reduce you to a victim, characterised solely by the hardship you've endured. It can turn your relationships into eternal games of one-upmanship where no one wins, and everyone hurts.
I won't live like that. But it's not easy.
I don't forget things - dates, occasions. Which seems to have turned into a bit of a curse as my brain endeavours to remind me exactly where I was and what I was doing two years ago. Do you remember Hammy? This is the day.... Do you remember? This is how it felt.

Nothing worth having comes without some kind of fight. You've got to kick at the darkness until it bleeds daylight.
