Don't believe a word of it! She doesn't know what she wants right now, and she might not know for quite some time. Leave her alone. Give her the space and time that she asks for. If she wants no contact, then give her no contact. I know it's hard...but believe me you will be better off if you do these things. Don't cry in front of her, or beg, or plead. These are all mistakes. I know your heart is telling you to do those things but DON'T LISTEN TO IT! Listen to your head. Those things will only push her further away.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
