I can understand from what you are going through at this point. If you really want to apologize for the things you said then you can convey your message from any of your mutual friend or co worker. If she still does not want to talk to you then you should definitely move on my friend. It will take time but things will get better with time. Try to indulge yourself in other things. Hang out with your friends. You might be worried for her but at the end, its her life and she knows better what to do with it.
