I have umm'd and ahhh'd about replying to this as I'm not really supposed to be in this section, but I figured I might be able to offer a useful perspective?
I think it depends on where you could move to .. if you can find somewhere you like, a place where you might be happy to settle, where you can get jobs etc then yes I would consider it (although since I'm in the UK I guess my opinion doesn't count much
)
As long as its to a place you can visualise a lovely new life (even if its short term (ish)
LTTTC is quiet stressful and emotional enough and I think sometimes the saving/scrimping etc that it can take may be the last straw .. if you know what I mean? We all fight hard to keep our spirit intact throughout this journey, and it is hard when its one blow after another seemingly without end.
I think that moving away from family etc is very stressful, but if it allows you for realise a dream (in your case a child of your own) then it is undoubtedly worth it (IMHO)
We are emigrating in the next 6 months so I know a bit about up-rooting and leaving family and the emotional strain etc. Ours is also to realise our own personal dream (kids included - hopefully) and it will be hard, very hard but in the long run, in light of the 'big picture' it will be worth it 10 fold (at least I blooming well hope it is .. if not ... we can always come home!)
