Past memories and past love..you remember it all too well..no longer lovers and became strangers,you met him again,but this time his heart was already someone else's

He had an accident few years ago and he doesn't remember you and the relationship you both had..he had a memory loss

You gave up on making him recall his memories with you when you saw how happy he was with his new lover..

He doesn't remember but you know everything all too well..
