I am married for 9 years and for the past 1. 3 yrs I am separated from my husband and my son is with him. Our problem is my husbands brothers wife she is a widow and she has a daughter. My husband helped her whenever she ask financial support. Recently she got married to another person and due to some issue she divorced him. And still my husband is helping her, but when I have a need he ignores that and prioritizing her. What should I do??
