Absolutely.Passing through the phases of it is what we're wired to do naturally. Impeding that process is what keeps us in pain.
I'm kind of stuck right now, an uneasy situation but nothing, nothing on the scale of what the O.P. is having to contend with right now. My 92 year old aunt (my Dad's baby sister) was widowed a number of months ago and now, she as well has passed. So now my aunt and my uncle are gone.
But my sister has decided we won't say anything to my parents about my aunt's passing. Mom and Dad are too fragile, sister thinks and probably she's right, but this puts the rest of us in the sort of limbo, as we try to imagine what we'd say if my parents ask if I've talked to my aunt lately. Part of me wants to celebrate my aunt's life with my parents, but another part of me knows that consensus is a precious thing when it comes to such things.
