Lisa, you must realize your (ex) friend is on drugs. When a person is on drugs, they do whatever they have to do to keep their addiction in full bloom. They also become a person that isn't very desirable. They become hateful, bitter, selfish, self centered, and make their drug their first priority. Please realize this isn't your friend, this is the drugs your friend is on. When/if she decides to get clean, I can promise you she'll be a completely different person, a much more desirable person.
