It's the first time I've come across this post - was that George me or another one? I don't remember as it was more than an hour ago
It was certainly something that was described in one of the sessions I went to in the support group I went to.
For most of us, the grief doesn't really diminish it stays just as 'big' but we grow bigger as our new reality 'enlarges' us and so it occupies a proportionately smaller part of our being. I've found over the last 15 months or so that it is happening to me.
One of the other things that was described at a group meeting was "The Whirlpool of Grief" (Google it). This is such a good representation of the process of grieving and it describes perfectly what I've gone through. After plunging into the whirlpool you go round and round and just when you think you're out of it, you're sucked back in again until hopefully, one day you re-emerge into the river of life and for the lucky ones possibly even find a new partner (not something I can imagine for me but obviously it happens).
I heartily recommend going to support group meetings if you are lucky to get the offer.
