>>507592820>Can't you just support her and tell her from the beginning that you aren't going to support her relatives?You can negotiate whatever you'd like between two humans, but as
>>507593003 mentions that might be a deal breaker.
Some negotiate just supporting their girl, others a fixed amount to her immediate family (but not extended senpai or variable), others are on the hook for a wide variety of incidents from random senpai.
If a guy took a pina back to his 1st world country and she worked even a basic job, she could take care of the family support purely from her own funds.
To mix all this up, a gal may say one thing at the start of the relationship, but actually hope you see her side later or simply be hiding the "bad news" while you increase your bond with her.
