My wife is used to it as it has almost been 20 years now. The kids get upset when i go but we get great quality time together when i am home. The toughest gig is when you have really young kids - the strain on the spouse is unrelenting and i don't know how they do it. We get to go to work and have fun (most days!) and they don't. I don't know how they do it.
The roster helps as you can at least plan your month. The Air Force didn't have that (as you were on call every day of the year) so it was demanding. I missed the final Crowded House concert at the Opera House as i was called to fly whilst on the train into town!
Ultimately, aviation is a single person's game. Trying to find pilots on their first marriage that has lasted more than 5 years is like finding a needle in a haystack. (Thankfully, i am one of them)
