It is good that you realize the things within yourself that need work! Everyone needs a bit of that:) I think you should talk to her again, because your feelings about this will not change. It is best to be honest with her and yourself, and I think if you were to just tell her exactly what you just said here, it might make a difference for the both of you. If nothing else comes from talking (ie: maybe you’ll have your good friend back, maybe it’ll be more of a serious relationship..etc..) atleast you allowed yourself to be honest and tell someone how you actually feel. Sometimes I think “would I be happy if today were my last day? Would I have told people exactly what I felt about them even though it frightens me?” I know that there are certain things I regret today that I did in the past. When faced with a chance to make it different, better, would I? I think you should just go for it! Either you gain back someone you lost, or you put that nail in the coffin and you’re set free from wondering.
