To me, the indication of love and hate can be seen in your first post to ask whether or not to forgive her. You may not wish to declare the love and hate strongly but the length of your first post shows a deeper emotional connection. You have been given advice to leave her alone as you can not change her. She will not be a better person for you. You will only entangle yourself in something far too complicated for your emotions to handle. But, it is your choice.
