Sounds you are doing well just don't tell her what you think she thinks. You are probably right, but WAW's are known to do the opposite, or change their mind just to prove you wrong. Assert who you are, what your thoughts are, and what your plans are. Inevitably they are all connected to hers she'll get the hint.
In fact it's almost better to say:
"I don't understand why you're doing this, but if you must there is nothing I can do no matter how much it hurts, so I must move on myself. "
This statement asserts that what she is doing is hurtful, that you are independent know, and most importantly by not "understanding" her motives you force her to stop and ask her self. "what are my reasons again?".
IMHO most WAW's come back when all the adrenaline, anger, passion, excitement of their freedom wears out. They are left sitting by themselves wondering and finally logically reasoning if all the pain hardship and stress they have created is worth it. Then they can look at you and hopefully see your changes and see that there might be a chance. Hopefully the DBing and GAL push her over.
If you tell her too much what she thinks you'll get this:
"he thinks I'm feeling guilty?! I'll show him"
You could be the best psychologist in the world and she still wouldn't listen.
