The past makes you who you are, whether you want to believe it or not. Those little life experiences teach you what you need to know to become who you are to this day. They shape your new morals, your feelings toward people, your attitude on life even. You can't just delete a part of your life. It doesn't work that way. If not we'd all be innocent, naiive and absolutely nothing. No history, story, no feelings or thoughts. But don't worry, the people that believe they can actually do that, are in for a rude awakening because by "erasing" a part of your life, you are just lying to yourself. And lying to yourself hurts so much more than when the people you care about lie to you. They will come around. Maybe not in time to fix things with you, but at least you can be sure that the person you cared about is not stuck in a bad place for the rest of their life. And you can only hope that they don't lend up regretting the things that they say.
