How would you feel about working away for days at a time? Leaving dh and kids? Even if it was lucrative and you would really enjoy the work itself. Could you or do you? I have done it before, but as a one off, not as a semi regular thing.
I have actually said yes in principle, btw. I am just starting to think about it now. And it wouldnt be for ages yet, so I don't know why I am worrying about it......
