I recall reading somewhere that it would take a minimum amount of time for them to feel loss/ take stock of what has gone on.
I think what I read referred a lot to like a honeymoon period where everything is new/exciting and the reality of what has occurred hasn't been realized yet. And at around 7-12 months (everyone is different so I wouldn't use a time frame) but I see it as about where I am now 7 months in. My W is not out of the fog but she is starting to peak out of it and see what is happening and I think it is really freaking her out. She convinced herself his is what she wanted and thought it was still what she wanted until I have started to disappear and not be around for her now all of a sudden it's getting real and she is trying to cling on.
One day at a time.
