How would my spouse be doing? He would have gone back to his home country after earning his degree, probably would have had a few heart-wrenching reunions with his ex-gf, then break up with her for good, be single for awhile, eventually find some one with a similar background to his own. He'd be less well off - would have been an entrepreneur, which eventually would have worked out okay but not an easy start. His mother would be breathing down his neck everyday.
I, on the other hand, would have explored a few "what if" romantic situations but eventually have figured out it wasn't meant to be with any of them and I probably would have been single for at least a few more years than I was. Likely would have been lonely during that time. Wouldn't have my kids and instead would be fulfilling a bunch of social obligations that made me find life dull and annoying. Eventually I might have abandoned the drudgery and joined the foreign service if I hadn't eventually found a decent husband after a few years in DC - though romantic prospects in FS wouldn't be any better than in DC. I'd be lonely. In better shape though, hopefully.
