Man, that is rough just to read, let alone to live through. I'm sending a virtual hug.
It really comes down to what your boundaries are. Are you willing to live as a Plan B and hope that she changes her mind again? It's a cliche here but love is a choice and an action. Your W is choosing OM and acting accordingly. You can choose to keep loving her and spending your emotional energy on her, or you can choose to walk away. I can't tell you what the right choice is. I will say that I have learned that we only have a short time here and you can spend your emotional energy and love on someone who isn't worth it - someone who is an emotional leach or someone who can't or won't reciprocate. Realizing that I was free to spend my emotional energy elsewhere was a breakthrough for me, and really helped me move forward.
