After only one month I already miss it enormously.
I am very glad you find these calls rewarding and I am certain she does too. I am going to have to find someone to fill this role in my own life again.
It sounds like you are steadily strolling the road of healthy grieving, I'm sure he would be proud.
Keep your head above the water my friend.
And yes -- navigating the line between the endings/beginnings bit, the loss (which it is), and tragedy (which it isn't) is difficult but this time around I am finding it easier.
One of the things I have already realised is that explaining-stuff-to-my-Dad is portable. I can do it in my head. And when I can do that without tears, I'll be able to add my Dad to any audience in the future, and hear his questions as well as theirs.
If I may be presumptuous as a stranger who’s grieved several special relationships to offer advice, please try to catch yourself if that pursuit/search feels like it’s looking for a substitute for your Dad the person. Whichever relationship like that comes next will be both familiar and unusual. It might still be worth pursuing even if it doesn’t feel right at first.
