Unfortunately it does take time to fade.... but on the good side eventually it does fade and it's really gone. With the affair 10+ years ago. My husband could tell me any detail about it and I have no feelings of upset, anger, nothing. So much life has happened since then that it seems a lifetime ago.
Cat, you are right about some of the questions being splitting hairs. I probably should make up a list and then think out what really might be helpful and what's nonsense.
There is no arriving, ever. It is all a continual becoming.
