What a wonderful bunch of responses
I think having been "away" from home for some time, really does shape you in many unexpected ways. For some, they find a spiritual home away from where they were born and some literally get to just "go home".
I am the Brit half of our marriage and I have come back to the US for a second time. The first time was dreadful, as newlyweds with unrealistic expectations and hopes, none of them panned out and we went back to the UK, worked hard to expand our skills in our professional lives so that if we could ever come back, the jobs part wouldn't be the concern it normally would be.
Everything has worked out wonderfully this time around (it's all in the timing, I'm convinced) and I feel so much happier and more relaxed here. Apart from the material side of life (which is important, it's no fun living somewhere hateful if you can't afford to move, even with the love of your life), there is something intangible for me this time around.
My husband has been able to re-connect with certain family members, my best friend is 20 mins away with her family and I love our new lifestyle, it's re-juvenated and revived our spirits and I personally have no interest in living in the UK ever again, even though some of it is beautiful, I can't actually afford to live in the beautiful areas or enjoy it for what it is, but it will probably always be "home".
We both have been lucky enough to get really great jobs, we have a small car and much like Sweetypeabea we manage and for us, it was almost instant and yet, right now...we are living with in-laws, so, not idea
So, to answer the original question...it felt somewhat tense waiting to get here, wondering endlessly about the unknown and how you are both going to handle it - but I think that's a big part of the process, it's important to almost "feel the fear and do it anyway", such a leap of faith in many ways and the rewards from that are great or can be.
I also believe it helps when, as a couple, you have both experienced living in the other person's country for a while, it just gives you a different perspective and you are able to understand and support your partner effectively for that experience.
Sarah, I know you have had some frustrating times in my country and you will be forever grateful for that, in many ways in the years to come, but try not to worry, you're coming home and you both will be just fine, it can be anything you want it to be this time, a new start, but in a familiar place. I always try to remember the people who don't get the opportunity to do this and think how lucky we are, that we can.
Good Luck!
