I think that being an American and living in America pretty much spoils other countries for you, in a long-term sense, anyway. Years before I had ever been to (much less lived in) Europe, my best friend went on a three-week trip to various countries, and when she got back said, "Europe's a beautiful place to visit, but I wouldn't want to live there." I certainly stopped taking the States for granted as soon as I moved here.
I think a lot of the women here are staying at home with children, and I know that can be isolating. I don't have kids, but I'm self-employed and work from home, so it's the same difference in the isolation department. In your case, your husband's going to Oxford, which means you're in a university town. You should be getting out and meeting people! Plus, if you're just here for the time he's at Oxford, you'll be going home soon enough. There's a light at the end of the tunnel.
Anyway, one of my brother's friends was attending Oxford as of a year or so ago. If he's still there, I'd be happy to put you in touch with him.
