First of all imagine how difficult it is for your W right now. She has put herself under pressure to feel a certain way. It must be reallly scary for her.
She has probably started to accept your changes but she is scared that the past will repeat itself. She is scared that once both of your entire focus is shifted from your relationship that she will be neglected and non-validated again.
Under all these pressures and anxieties it's no wonder she can not "let go" enough to fall in love again. It takes time.
My advise is to try in every way possible to accept her and what she is going through. If OR talks pressure her then avoid them. If she wants to talk about something then listen. Enjoy her as she is. Let her know how much you enjoy kissing her, (even if she is struggling with the passion). Assume and believe that she wants to fall in love with you again but let her feel comfort in the fact that it will not happen today or tommorow that it will take time and you will wait and support her while she makes this most difficult of journeys
By the way I could have written your last post (only a few months ago)
