Well, we're still in the honeymoon phase (married last October), but honestly being married has been so much better and more fun than we even imagined. It's been slightly difficult at times adjusting to living over here, and trying to find a job at first, but the being married part has been easy.
I think the biggest change for me is that I've become a lot better at picking my battles. Knowing that this is the long haul, I just don't find we have the energy for little fights. Of course, they happen from time to time, but not very often.
