She is on her own emotional roller coaster right now. She is quite probably second guessing herself every step of the way. Try to do what you have been over the last while , what drew her back to you again? Make sure none of your old negative behaviours creep back in if you are getting complacent when she comes close. What does she like you to do ?
My guess is you are going to get tested for a bit. The more you stay on your path the more she will respect you and trust you.
