Just wanted to say hi and welcome to PIO!!
Can understand your predicament, its always harder when one of you is so keen and the other needs more persuading. I'm sure she can see the benefits there for all of you - its just such a big scary leap to make! If you already have your visa in place, then you owe it to yourselves to give it a shot after all the time and effort you have put in to get that far.
Perhaps you could persuade her to come on here and after chatting a while, we might be able to push her in the right direction for you!!!!
Good luck with whatever decisions you all make.
