I think you deserve closure, that is such a strange end. You deserve to state your feelings, let them out of your heart, there is no need to be mean on purpose but you should definitely state your feelings and say what you really feel. It is the least you can do, just being led like that. I understand a little what led to her behavior as sometimes we want to cling to someone/something even if it’s not what we want exactly. Who may know for her behavior but you are entitled to let her know how she hurt you and that your feelings aren’t to be taken lightly, I think some clarification is good. No harm in that, even if it just for yourself.
