Assalam Alikum, I wish to hear your views on a sensitive topic. I am posting on behalf of my mother who has asked me to find out if she requests my father to end an illicit marriage he made whilst in Bangladesh, would be a sin on her part. My father makes regular trips to Bangladesh and recently we have found out that he married another woman over there without my mother's permission. We are a family of four, and should his priority not be us first? If anyone could reply saying whether or not it would be a sin for her to force him to end the relationship, and secondly how me, my sister and my mother should conduct ourselves towards him knowing what we know, would be hugely appreciated. I thank you all for your time and look forward to your replies.

Regards,
Anon
