Because quite frankly what you state is a load of bollocks. Sure it's not easy, but with a little effort swapping you normally have half the month together. Co-ordinating leave isn't easy, but its achievable. You can pax on a flight with her to a destination your fleet doesn't go to...makes for a fun night away, and pretty cheap with the hotel paid for.
Nothing's easy in life, but with a bit of effort you can make it work. ...And that's speaking from experience.
