When you really let go and get to a point where you are ready to move on, then the opportunity may arise.
The 'moving on' is the part I struggle with. As a Christian I don't believe in divorce or remarriage, so I'm in for a single life if my W and I never reconcile. (I won't divert the forum by going into the scriptures behind that, but google 'john piper divorce remarriage position paper' for a succinct but thorough analysis that pretty much explains it.)
Perhaps I shouldn't be so hung up on wording, perhaps I should just take Steve's words as 'ready to live life solo'.
