The future that you knew was coming is now here. Use this time to start doing things you put on hold for so long.
Also use this as a time to develop the next phase of relationship with your daughter as an adult now. Start to plan for your roll as grandpa.
Wishing you all the very best

Your story sounds a lot like mine. I was married we had a daughter. I have lived most of my adult life single. My daughter’s # 1 phobia is spiders. If she has a problem with many things I’m the one she calls and I run over to help out , but by running over I mean going down a couple of doors to her place.
Both my parents past away 20 years ago just as I was starting to raise my daughter.
A lot of similar things and a few not so similar.

Parenting is this weird job where, if you're good at it, you become semi-obsolete before you're ready for it. She'll always need a dad but gradually, she'll do more things for herself, which needs to happen.

It's a hard adjustment for the parents.

An hour away isn't THAT far.
