I agree with Inky that this girl is NOT ready for a relationship. She was telling you and showing you all along and it sounds like in hindsight you can see that. Good for you! Your best bet is probably to move forward and find someone who is ready for a relationship and let go of this one as lovingly as you can. She is still working through her baggage and has not done the work you have to get over her past. Focus on finding someone who has done the work. Best of luck!
