This is really none of my business, but...
I hate to step in where I shouldn't, but you're being horrendous. This person is not bullying or harassing you: you shared a story that is not appropriate on this site, then made her replies about you being the better person. You are not morally superior here, as a matter of fact, you are behaving in a truly vile manner. You have no place telling someone to leave the site when they have done nothing wrong. I sincerely apologize if this hurts you in any way -- please, just try to consider the feelings of others.
