I am a bit over the three year mark and although we didn't have kids I do feel that rebellious side.
I think the true reality , even if delayed , seems to creep in at this timeline.
This is our new life and I just didn't want it to be the truth.
So be kind to yourself and do what you need ..pitch a fit , yell as loud as you want , do whatever you need to do.:)
It has been said before grieving doesn't have a timeline
