First off, have a wonderful time at the party tomorrow. Don't you worry one minute about if she is coming or not coming, and what to do if she does come. YOU are doing a terrific job. YOU know what to do. Spend the time with your friends who have open their arms to you. I know you will have a wonderful time.
I bet you if she even shows up, she will not stay long. She will notice you are there and see all the great changes you are making. She will notice. Friends will also notice if she does not show where they stand in her life. Gambling vs friendship.
Now the second issue. Don't respond to that whole facebook thing. Just reply thanks so much for the birthday wishes. Be the better person, and that is it. Nothing more, boy that is just like a big sticky mess of glue. I cannot tell you what to do, but my head says don't. It will just get spun out of control. That whole thing sounds like more of a face to face conversation.
Have a wonderful time at the party
