Dingo, sorry things didn't go as you hoped, but it does sound like your W needs more than one good weekend to figure out her stuff. I think the fact that she is contradicting herself is a good thing. It means she is confused on some level. And it may be excuses, but it's probably the truth that she is having trouble giving up the OM, even if it is what she wants.
I wouldn't ignore her calls and texts - that's just being cold. However, I am not too well versed in how to handle a WAS in an A situation, so I am sure someone else will weigh in on that!
