If Jen is actually in the UK, Tom, his rear party's going to be missing out.
One bad joke leads to another. Sorry, Jen - I know you wouldn't.
But seriously, that two-country thing could also be part of the problem. I met my first wife in BC. I dragged her to Moose Jaw and then Pet, where we subsequently separated. Her mother had died and her father moved to a smaller town with limited employment prospects for her during that time, so she would have had a rough time getting re-established plus we really couldn't afford to ship her stuff that far either. She stayed in Ontario for a few years, and then went back to BC later.
I lived with a young German girl while stationed in Lahr. It was a pretty good relationship, but not 100% convincing - not enough to marry her, take her to Canada away from her family, friends, country, and culture, and have her stranded here if things didn't work out further down the road.
I remember being pretty homesick too for several years after my family immigrated to Canada from England when I was nine, so that was probably a major factor in my decision as well.
I did not want to uproot somebody else when I wasn't completely certain of permanency.
There could be some of that in Jen's case.
