This is what many fail to do, and then find themselves going down the same path, because of baggage, that they never really 'let go' of.
I think we fail to distinguish between the memory of something and unresolved issues. Obviously, we'll always remember a certain situation/relationship/time in our lives. Can't change that, but if it's still got its hooks in you, chances are there's something unresolved that you really need to work on before whatever's supposed to happen next in your story happens.
Thanks! Just an aggregate of thoughts that were pooling around my brain anyway, so glad to have somewhere to share them ;)
