move on
don't invite her to your b-day
i'd cut if off cold turkey, don't respond to her texts, don't even communicate with her at all. That will be tough initially, but after a while, you won't even care. Thats the best way (IMHO) to forget about someone. Don't let her jedi mind trick you with the whole "friends thing". That will make you more miserable. Get involved with something such as focus on school, job, a hobby, or go to MFest, etc. Find something to get your mind off the subject.
Just move on with you life, where ever it leads you.
