Ronan, well, many Brothers can understand your situation, so can I. It is "difficult" to be far away from our lovers/wives.
I was talking to Lyian before yesterday about Christmas, saying it was very beautiful, to share a big dinner with family, and seeing kids opening their gifts and so on. For sure, I would have liked her to be here, too, with me. But she could not. She also told me that Christmas is not as important as in western countries, but that she missed me many days, not that one especially.
I think too, that we chosed to live our relationship, to find our love in China, while many men can find love around their home/work...
So we know what have to face, day by day.
but keep your smile UP, because you know you will be soon with her, and maybe that, next year, you'll both be together forever. Who knows?
