From what your W has said, reg. hugs, kisses and ILY, i get the impression that she is really reaching out for some affection and love. I know tha once bitten twice shy, so it makes you stop offering your affection when the rejection factor is high.
Do you think your W might be suffering from depression or some sort of physical illness? Her rampaging reminds me of when my H was in the deep dark depths. Sometimes all he wanted was for me to hold him and tell him I Loved Him, but yet he would push me away if i attempted to. It's a hard sitch.
Where you very affectionate before this? Is your withdrawal a sort of more of the same? To me it seems like you are very withdrawn from your W and i can understand why this would be so. However, total withdrawal is different from detaching.
Do you still love your W? If so, how can you communicate this to her?
Just another question: What are your goals? How do you know if you are achieveing them? What will be the first sign that your W is thawing?
These are the Q's that i have to remind myself of in order to keep going forward.
I agree with some of the others with the X issue, maybe next time surprise her with your response!!!
