From the sound of it, it seems that W got to call the shots on her return. A comeback with pomp and circumstance.
Having his number on her phone and as a FBF is a definite NO NO.
As everyone is saying, YOU make the ground rules and get ready for her huffing and puffing and eventual crying. By rules I do not mean control her but establish where who and what you will accept to believe her. I suggest to never let her call the shots.
Don't be manipulative, just firm and sincere with yourself and your feelings.
If they want in and really do want it, they will let you know.
