Will it always haunt the dumpee for the dumper's decision?

Will being dumped for whatever reason always haunt the dumpee? Will they always go back and think what they could have done to stop things from ending? Will they always live in regret and wish they could have done better? Been a better person? 😢

I made one little mistake and I just wonder if I just had kept my mouth shut would will still be together now?

I know I need to let go and I have for the most part. But certain songs bring me back to him and then I get to thinking what if.
