Coping with BPD: Here are some links that might provide some clarity: http://psychcentral.com/blog/archives/2013/11/15/living-with-loving-someone-with-borderline-personality-disorder/. http://www.borderlinepersonalitydisorder.com/family-connections/family-guidelines/. http://www.mayoclinic.org/diseases-conditions/borderline-personality-disorder/basics/coping-support/con-20023204

Learn All you Can!!!: Oh, boy. If that's really the correct diagnosis, you're in for quite a ride. It is what is called a "core personality disorder" that is almost impossible to treat effectively. Not that there is no hope, but it's quite a job dealing with the situations that may come your way. Seriously consider just how committed you are to the relationship then go from there. Wikipedia has a good description

Borderline PD: Remember that she is much more than a diagnosis, and often people get this dx who would better be described as having complex trauma. Treating any trauma history is a critical part of the person overcoming the issues that drive challenging behaviors. Suggest you go to at least one or two appointments with her at the therapist to get some professions guidance on healthy boundaries.
