My friend, you are changing and if your partner is not willing to participate in an evolutionary change, lets call it a Quantum Leap, that is her problem. It is sad, but it is her free will. Respect her, love her, and let her go.
As for you consider having her in your life a gift. At the same time life is like a glass if you want to fill it, it has to be empty and preferably clean. You perfect partner will arrive just give time to it and enjoy the ride and the freedom.
