Feel for you. Can't imagine what to do in that situation. Can totally imagine how social media enabled a lot of that. I'm in a similar situation where my wife joined me in China because my job is over here. She's making a go of it focusing on studying and learning the language at the local university. She's really focused hard, all I ever see her do is study. So far she's happy, but sometimes I worry that she'll become unhappy. We're on the lookout for opportunities to develop healthy relationships with other people so that we're not alone (especially her, as she's new in this country).

Think it's really important to get involved in a local community where you can forge high-quality long-term relationships with emotionally healthy people whenever you move to a new place. Loneliness can kill you otherwise. For me, it'd usually be a church where I can focus on developing myself personally and spiritually, as well as bonds with others in a really non-judgmental environment. Realize that's not for everyone, and that many people actually experience church to be a very judgmental place. Sorry to anyone who's been through that.

Sounds like you're still supporting her financially. Don't know if you're hoping to get her back, or if you've given up and cut her loose. It's possible that the only thing you can do is cut her loose at this point because you're only acting as an enabler. I am not a psychologist. Wish you well. edit: realize from the other comments, maybe alimony is involved. If so, very sorry to hear. IANAL, but that sounds like a really raw deal where you should consult a lawyer, if that's the case?
