I don't know. She might be waffling inside and saying something different to you because she is still, admittedly, angry. Move forward on the zoo date at some point, don't file the papers yourself on the divorce, and see what happens.
If you can afford a few sessions, make an appointment for a counselor to address this issues she brought up to you. She will be surprised that you are taking them seriously and take notice. Also, you will find out if her complaints have any validity and what communication skills you can learn to fix them. If you have a few issues to work on, you will be fixing them for either this relationship or your next. Then if a the next wife says the same things and you have worked hard to fix them you will really know it is "her not you."
