How can one reconcile financially supporting a husband beyond his personal allowance, the family's desire to intervene out of fear of exploitation, and maintaining the marital relationship and peace of mind?

The solution to marital problems lies in the non-interference of relatives, and in resolving marital issues within the framework of the couple themselves. Marital maintenance is solely incumbent upon the husband, and the wife's contribution to spending is by mutual consent. Both spouses must treat each other kindly and be patient with each other's shortcomings. Furthermore, obedience to the husband takes precedence over obedience to relatives if interests conflict, while still showing kindness to relatives and striving to reconcile viewpoints. Above all, it is essential to seek Allah's help and supplicate to Him for reconciliation between them.
