Assalamu Alaikum 
I have felt that my relationship with my mother in law has been great Alhamdulillah. I have been married 4 years now. 
However recently she has mentioned to her son that although I have never disrespected her and that I am always helpful in the house – she does not feel like I am a daughter to her, she says the relationship she sees me have with my own mother and cousins is different to how I am with her and that I do not treat her like a mum. I am unsure what to do in this situation and if I have been sinful at all. 

Please can you keep this question private. JazkaAllah
