Oh, Suzie.....that is so hard to hear. A lie is always hard to swallow, but one from someone you loved and trusted that you can't even confront is sooo much worse. For your own piece of mind, I would give yourself a couple of days to just be mad. Then, you need to
forgive her, and allow yourself to continue to grieve her loss. She did what she thought was best - out of love, denial, or fear...
