I agree about the touch stone
OP Feel what you feel, and react however you need to - that is your prerogative no one has the right to dictate that to you.
It's not just the physical presence... its the fact that they have been in the background all your life, a sense of security that there was someone older and wiser who had your interests at heart..
It leaves a gap, and its the end of an era, things will change as people accommodate themselves to that gap Life suddenly becomes a bit more uncertain. If this comes on top of an earlier bereavement, it can bring the feelings from the first one to the surface again.
Even if someone is very old and it is expected. When it actually happens it can still be a shock. Its the finality of the thing.
If your Dh was saying it to comfort you, he has probably not experienced a similar loss and may have been trying, although clumsily, with good intent.
If he's saying it because he is tiring of your grief - after just two days and before the funeral - that's another thing entirely and he should have more respect.
It is often said, but I do think its true, that time is a healer. I don't know about that, but it does make it more bearable to live with. Give yourself time xx
