Every time there is good progress you have to be prepared for the pullback. It does undermine their vision of how their life will be better without you in it.
Just as much as you are going through periods of loneliness and depression, so is she. She just doesn't want to let you see them because she is trying to be strong and independent. You don't have to feel sad for her about it since she put herself in that situation, but do try and remain empathetic and understand that this process if painful for both of you and will cause both of you to grow and learn so that you have the potential to form a new, healthy, interdependent relationship.
Don't let her choice of words and remarks get to you. Sometimes she is trying to convince herself of things more than convince you.
Your frustration is normal and natural and totally understandable. But don't let it sabotage your progress. Find constructive ways to get rid of that stress so you can deal with her and let it roll off your back.
