Hopelessboyfriend- May I ask you how much you actually understand about PTSD? Ptsd can mean a wild list of what most people would consider as crazy.
But meanwhile, you have been answering your own questions as you ask them. She has been in relationships since her trauma. Yet she will not meet with you, not under any set of circumstances in which you have presented of which all are safe options (such as meeting her with her friends or family members present), and even went so far as to giving you an incorrect address. I can not speak for what anyone else would or would not do, but if I were concerned about giving a man (or any person for that matter) my address, I most certainly would not be inclined to giving him an incorrect one! I would just let them know that I was not comfortable in giving it. Paranoia doesn't mean that you have to mislead and allow someone else to make a fool out of themselves. Enough said.
PTSD does not give a person the excuse to treat you like their toy- playing with you while they want to, and tossing you aside when they have lost interest. That is something else, like behavioral issues- not PTSD. She may well have PTSD, but some of the ways that she chooses to behave cannot be excused by PTSD.
What you see is what you get, and if what you see is what you want, then keep doing what you're doing until you can't anymore.
