I think she has got a good point, if you are BOTH long haul then you may not see much of each other I know several couples with this problem, however if you do not aspire to work for BA / long haul airline then it should not be too much of a problem. Most charters (SH) and LCC's you will be at home tucked up in bed every night (apart from when you are on a night flight !!!!).
If you really want to fly, then you will, I suspect that if I had been in your position then I'd use the 'We'll cross that bridge when we get there' attitude !!!
