I have become very used to my sitch and yes- even to the point of obscessing.
The difference now is that it's not tearing me down like before- I am seeing that she is broken, and I am seeing that although I am thinking of her while she is definately not thinking of me- that my thoughts are no longer "woe is me."
You are absolutely right- it is better for me to not concern myself in anything having to do w/ her.
