Really upset

My best friend sense the 7th grade told me she isn't going to be at my baby shower because she has to work. Mind you I feel like she hasn't been there for me through my pregnancy at all and that we are growing apart and then this! I feel like it would be an acceptable excuse if I hadn't told her the date and time of the baby shower in September!! She had more than enough time to take the day off and she works at a pizza place that I too used to work at so I know if she would have given them two weeks in advance they would of gave her the day. I'm so upset and hurt I don't even know what to say to her what would you say to your best friend?
