I feel like that sometimes, too.
I travel a lot for work too, and my schedule is so random, it's not like i can plan on seeing someone when I am in the nearby city they live in, etc.

The guy I'm dating is really busy too and he travels a lot too so it's hard.

Sometimes, I think as adults it's so hard to not think about what others have going on in their life - kids, spouses, job, etc.
It's not like when you're 13 when all you had in your life was school and everyone was basically on a same schedule.
