Write her a letter telling her all the reasons that you don't want to be with her anymore. Mention all the rejections, the negatives, the rudeness, the ignoring, the lack of honesty and affection. Write it carefully, reread it, and then burn it (safely) along with photos, and other flammable mementos. Delete her from you webmail, phone contacts, and don't leave a trace -and don't look back. I am a licensed psychotherapist and this is advice I give to my clients. Warm regards, gentlefriend.
Thats a good question for which i need an answer too :/
Find something that keeps you busy, and move on.<br />
Remember....they don't love you, you're better off finding those that do.
