Can imagine how you felt when you wrote this, but sleep on it - for a few weeks at least.
Maybe it's not a case of not wanting to give it all up for you, maybe he's worrying that he won't be able to provide for you-look after you over there, male pride and all that.
Maybe when things are less tense you could plan a holiday and see how the family like it there. A leap towards something a little familiar is less scary than a leap into the unknown.
Our experience is that I always wanted to travel and my hubby didn't - said no. After months, when I let it drop, he made the decision himself and we took a year off and went backpacking around the world and loved it. Just needed time to work it through. After that, and seeing a bit of the world, the decision to emigrate naturally evolved. We'd spent 9 weeks in Oz and then a year later had a three week holiday (Nov 2004) and it wasn't til June 2005 that we started the whole process.
My hubby had similar worries to yours. Everyone is different, and I can remember how upset I was when Hubby said he didn't want to travel, so I'm not taking sides here, just thinking aloud I guess. I'm not saying give up the dream, but maybe take some time out for both of you to reflect.
I hope things work out so as both of you are happy and in the meantime, take care,
Love Jo
