I suspect that we may be going into the thread with different social assumptions (if this is the same relationship):
I do NOT presume to speak for the marriage and cultural assumptions of that culture and nation, and wouldn’t be surprised, rather, I would expect that it be rather different from what I consider the “norm” here in the US, which in it’s own rights, has hugely different assumptions across economic/social and religious groups.
Speaking entirely anecdotally, about some of my wife’s friends of Taiwanese and Saudi extraction (Not remotely the same, but to illustrate the differences) the gulfs of understanding when all parties try to communicate the norms left both sides shocked between expectations regarding living conditions, children, deference owed in-laws.
In other words, using the term marriage is correct, so many of the assumptions, responsibilities and roles were entirely different despite the similarities at the base.
So I’ll leave it to the OP to try to clear up the assumptions and responsibilities in their relationship across the board (especially with the earlier mentioned family issues) before I given even my ham-handed advice.
