You're probably joking, but in the article it states that these people showed Xi around Iowa like 40 years ago when he was part of some farming committee. They left such a good impression on him that apparently they've stayed in touch. It's really sweet honestly. In the article he says something like "to me, these people are america"
lots of good advice here. I agree with the sentiment that having a SO won't make you feel like less of a loser.
But here is my two cents. I think the point of being in a romantic relationship with someone is to hang out with someone that you like and who likes you (and, you know, have sex if you're into that). Really not much more to it than that.
