I'll give you a child's pov. My father worked 800 miles away m-f for 2 1/2 years. Brother was a toddler, I was preteen.
I just understood he was working. Saw him every weekend and just got used to that. It wasn't until years later I saw what my parents went through. Was much harder on their relationship than with my brother and I. He ended up leaving that company rather than stick it out and found a better job locally.
I appreciate you offering that perspective. I'm confident my wife and I can handle things just fine for our relationship, but the kid part concerns me. Thanks for that.
