Hi- I used to be an Executive Manager and regularly clocked up 75 hours / week 48 weeks / year. The balance I have struck is to fly regional jets in what I call a 5 to 9 job (6 to 10 actually). The pay isnt as good as the big boys (a lot better than I was on as a manager) I am,though, at home all but 2 or 3 nights /month.
Regarding trust shouldnt be a problem initially but once she gets married and lets herself go (as seems to be the way with British girls) the seven year itch, when you are out on the town with some attractive young girls, can become a problem. Checkout pilot divorce stats before convincing youself it will never happen to you. Go for it anyway....your a long time looking at the lid.
