Blondie83, I had a friend like that but after lies after lies I just blew and told her everything. She admitted all the lies and said that she hated her life and made up stories to make her life sound more interesting and exciting. I told her she was my friend for who she was and not for what she said she had or done etc. We are closer than ever now and she has got alot better. You just have to confront your friend otherwise nothing will change.
Eash... have you heard back from your friend yet. I agree with the others and ring her. Sort it out. Not worth loosing a friend over a misunderstanding.
