I experienced this with my ex partner, we were together for a very long time and eventually we moved to his home country, bought a house there etc. This was after many, many conversations, I was generally pretty open to living anywhere, but due to language issues (I’m fluent in his native language but he never learned my language), job opportunities and other reasons it just made the most sense. Eventually (after 6+ years living there and over a decade together) I found out he’s been cheating and lying about many things the whole time which was awful, but the worst thing was not having a single person to talk to because all our friends and family in that country believed his lies and sided with him. I spent more than a year completely alone and deeply depressed while trying to sort out the mortgage and other financial obligations, paperwork, closing my business and so on so I could leave the country. It was very, very difficult. I doubt I’ll ever be able to trust anyone the same again, but even if I did, I would make sure I protected myself (primarily financially). That being said, my view is probably very skewed due to the betrayal I experienced from multiple people, but I really do feel that the person that moves to their partner’s country is in a much more vulnerable position. Also, in my case, they started acting differently after moving back home and they never had any consideration or appreciation for the sacrifices I made to live there.
