I personally would want people who I know and love while I am alive to forget me and move on with their lives after my death.
It’s like I would be happier in whatever is in the after life to see the people who I cared about happy with their lives, instead of getting sad whenever they remember me or worse yet, remembering me on yearly basis after I am gone.
I genuinely find it very illogical and selfish for people to want everyone to never forget them long after they are gone, especially due to the pain that come with memories.
That is why I am curious about the reason.
Because that is what emotionally healthy people do when someone they love dies. They remember that person and are aware of the positive impact they had on their lives, and grieve that the positive impacts that this person had on them and the world do not continue. Grieving is hard, but the pain does fade with time, and the positives of the memory eventually overshadow the negatives.
