Why can't I ever be good enough for anyone? because you don't believe that you are...otherwise, if you did you would'nt need someone to tell you to drop that superficial playboy and find someone who will "bring something to the table", and who will be there for you when you need them. the best advice here is to start making an investment in yourself and your self esteem, get some good books about codependancy (co-dependant no more is one) and read them. If you truly want happiness in your life, it has to start with YOU sister, a bank wont give you a loan until you prove that you don't need one, relationships are kind of the same. Good Luck To You, remember,we teach people how to treat us
