It's incredibly hard. Possibly the hardest thing you will go through. Your W sounds very confused, back and forth, so all the more to not play much into what she says.
I know it's WAY easier said then done, but just try to give her her space right now. I am not sure how to handle the on and off affection, my H went totally cold, but maybe someone here can give you advice on that.
Hang in there. You will need to dig as deep as possible for patience.
