She may just be putting up her guard in fear of feeling hurt again. It's almost like she is trying to distance herself but in times she is letting go of that distance. When she lets go I can't help but think it is do to attraction and the deep love she does have for you. Keep trying I think you are doing great.
CSW.......Maybe you could make plans with her for her b-day. Tell her you would like to take her out. Or maybe plan a special day and tell her you have done so.
