Don't sweat it, relapses in negativity are typical. She had to do a lot of self convincing to become a WAW. She had to thicken her skin, and harden her heart to be able to walk away. She convinced herself there was no love, when there most likely is at least some left. When she gets close to you some of these protections get pulled away, and she feels vulnerable and exposed. Thus she backlashes in order to feel safe again. Remember to validate her feelings during this time, and let it pass without going into pursuing actions. In a way it is true that she shouldn't do this out of some moral obligation, and instead should choose to willingly do it. Otherwise she will never truly open up to you, and resent you for "forcing" her. That's why it is always recommended to forgo R talk, it forces the issue and makes them feel cornered and pressured. Sound like what you are doing is going great. Expect the negativity rebounds, but enjoy the moments of bliss.
