To be honest I thought I had accepted it once the papers were signed. And I have become far more detached than I was, now that I know that for all his talk of "I don't want a divorce, I just don't know how to fix things" he ultimately decided not to try and stay married...
However in the spirit of honesty just signing the papers does not mean I or anyone else have fully accepted the end of the M. That is a legal action which ends the marital contract, so to speak. But acknowledging internally that the marriage is over will happen on your own time table...
