We currently live in (removed) and have a comfortable life here. My husband talks about settling down in (removed) in the future, however I don’t want that as my family resides in (removed), and given the political differences between the two countries it is difficult to travel to and fro easily. And will be difficult for me to visit my home country.
To this he replies that if he wants he can keep me in (removed) against my will as religiously it is permissible and also if a husband wants he can stop his wife from meeting her parents.

I want to know the religious perspective on this, can a husband keep his wife somewhere against her will and wish?

And to what extent this is true that if needed a husband can stop his wife from meeting her family.

Your question has many facets to it to answer however In marriage both husband and wife need to discuss these issues openly with amicable and joint decisions. Communication is the key in any marriage. I would advise you to have good communication with your husband on his regard and you need to educate him about the rights of a wife and silatu Rahm.
Islam does not at all show any injustices to any gender and it is a very balanced deen.
I think you need to use your power of communication to ensure that he respects your views and opinion. You too have a God given right and you need to use it wisely.
Talk to him and share your concerns. I’m sure he will come round it and will value your opinion.
