S/O Lifestyle
Hi there HKguy,
You seem to have a pretty good idea of what the SO lifestyle is about.
If you are a very family orientated man and want to see your kids growing then I'm affraid to say that perhaps becoming an airline pilot is not the best choice for you, specially doing the long haul stuff.
If staying near your family is very important to you and you still want to enjoy the freedom of the skies than perhaps you should consider a career with an airline that does mainly short haul flights. There you are more likely to sleep at home everyday.
These are only my opinions but I think that at the end of the day this is a very serious matter and it is something that you and your wife should spend some time discussing about.
All the best
