First, do not keep asking her if/when she is leaving. If she is going to leave, she will. If not, she will stay. No point in putting pressure on her, or bringing the subject up. Also, I would quit saying hi to her in the morning etc. I know you want to be be civil, but she wants nothing to do with you....civil or not. So you need to withdraw from her completely. Detach from her to the point where she does not know you are a constant Plan B. Doing so will help eliminate your fear of her coming back for the wrong reason. You are a Plan A kinda guy, and it takes work and effort on her part to be with you. Remember that.
