What you're going through is sad and rather hard to bear in the beginning but with time and what you do with your time, you'll get over her and go onto meet someone else and love them as well... the beauty of that as that they will love you back.
After 10 months she should know if she loves you or not and if she did, she would have been very happy to hear that you love her.
If she breaks up with you tomorrow then tell her that you don't want her to contact you because zero contact is the fastest way to quickly get over the pain and arrive at the stage of indifference to her so that you're not hurting when you see her or hear about her anymore.
If she wants more time to see if she can get on the same page as you then you'd do well to do your best to calm down your own emotions over her and let her catch up to where you currently are in feelings. It will take you letting her do most of the initiating and being less available to her in the future for that to happen. of course when she wants to see you, you will continue to be attentive both emotionally and physically with her.
Good luck... let us know what your meeting is about and how it all turns out.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
