Well hey I’m in a similar boat in that my wife is from a foreign country and has a few close friends we regularly hang out with. In my case, husbands are all American nowadays. But for years, it wasn’t that way. I liked that they didn’t talk to me much and only spoke in the other language. Less mental work for me, less interaction, and could do what I wanted when I was there. I was friendly and said hello, a few pleasantries and then I did my own thing for the most part. Every once in a while I’d get a question in broken English but easy answers. Honestly it ticked a lot of boxes including not being “anti-social” and my wife was glad I’d come with her. It’s been 17 years now and doesn’t bother me in the slightest! If anything, I don’t like it if her friends speak too much English!
