Quite easy, brother... Go to Doha, see it by yourself and compare to what you have here in Brasil and what you would have in Europe.
I believe you're flying for AVB, right ?
We hear a lot about the working conditions in Low Costs around Europe and probably a lot it's true, but remember, EUROPE is EUROPE. A great place to live, a lot of things to do, cultural values close to the ones you have etc etc !
On the other hand, flying for Qatar seems pretty nice ! No one flying here in Brasil could deny that. Good money, top notch aircrafts and a great improvement to your career, widening your horizons !
But you will still have to live in Doha ! It's nothing like we're used to here in Brasil, nor in Europe.
When going there, try not to stay only at the Pearl, take sometime and talk with one of your friends there and ask him to drive you around the city.
Now, try to picture yourself living there for the next 15 or 20 yrs ! That's probably the time you'll have to stay there to make it worth. If you think you'll be happy there, that your kids will have a happy life and your wife will be able to put up with all the differences, then, go for it.
Otherwise, just stay where you're untill you can find a great place to work in Europe.
All the best !
