AFWAW....NO your wife is not pursuing you with those questions...what she is probably doing is trying to create the sitch where YOU DO go on a date with someone else so that then her guilt will not be so overwhelming, and also she probably secretly hopes that you will fall for someone else so that she will not have to make the decision, YOU WILL....
My two cents....
I'm so sorry. I am praying very hard for you. But seriously sir, your wife is too far gone right now for you to really hope for real communication from her. Her phone call is just further evidence that she's not done screwing around (ie: the reason she cannot make up her mind), and that she is feeling guilt. However, guilt does NOT mean a person has remorse or contrition. It just means they think that by feeling guilty, they can somehow lessen the effect of their bad deeds.
