Someone who hurt you in eighth grade can be different at twenty. So can you. Leave a little room for that.

People at fourteen are not finished, and that includes whoever made your life harder. Most cruelty at that age comes out of a kid handling something badly rather than a settled character, and six years later they can be genuinely unrecognisable, the same way you are. None of that obliges you to forgive anybody or to let them near you. It only means the old file may not be current.

You might hold the question open rather than closed, which costs you nothing. If somebody turns up changed, you can decide then. And give the same allowance to the version of yourself you are embarrassed by.
