ANSWER:

She shouldn’t be free mixing with men who are non mahram.

If she is not living with them in a joint family system, she can demand from her husband a separate home as this is her right in Islam. 

If she is already living separately, she is not obliged to ever meet them. This is better for her heart and she doesn’t have to see them or be with them. 

QUESTION: What should be the general behaviour of a husband towards his relatives&siblings who openly hate his wife, insult her and want him to divorce her? My husband remains quite on spot when i am insulted and later confronts them in my absence.This hurts me.Also, he will be angry for a moment but after a few days will be laughing with them like nothing happened.So, they keep repeating it.
