Like I totally get the being sad aspect of moving and being away from loved ones
I understand the discomfort of the unfamiliar and a desire to cling to the past
None of that is in question, this isn’t a calculation

What I don’t get is the dramatic over reaction
Or the lack of preparation when you know how you are
So for example, I know I’m a lazy ass and that babies take up a bunch of time
Before she came home I canceled my gym membership and bought a full weight set, because I knew good and damn well I wasn’t gonna make time to go to the gym

Now take my wife. I was home for four days before we got on the road
She has literally months to prepare to leave, so see people, dinners, drinks, lunches ... and she didn’t with some. Some she definitely did. But she didn’t make even an effort to do some that she bemoaned in those four days
These are the kinds of things that I don’t get.
And I also don’t get the aspect of recognizing something and not doing something about it
My MIL for all her faults, gets it.
She already has a ticket for next month. She’s planning a trip for November. She has a retirement plan ready to launch and is now passively looking at houses while we figure it out. She gets it. She doesn’t want to feel the way she does and wants to change the situation. My FIL has none of the above
He has no clue how he wants to handle this
