<font color="#000088">I think it may just be part of your borderline traits bothering you. Maybe if you focus really hard on how much you really care for your new boyfriend, than the bad feelings may subside after a little while. Your dream may have just triggered the hatred, and by focusing on the positive that you have now, may relieve your feelings of hatred towards your ex!
I hope that helps you feel a little better!
