No More Talking

Hi ladies,
I want the answers when my inlaws will question so I will give the details please give me suggestions or please the exact way to say it....

I have completely stopped talking to my inlaws n it’s been many months..
I use to occasionally talk but my last thread me n my husband fighting he told my parents but till my parents pick the phone he called his parents n said n asked to tell my parents so inlaws got good chance n spoke to my dad but my dad did not say much but did tell me saying y is she fight with my son wen he works hard come home tired n listen to her she is educated put attention to the kid .. I was mad n that was it after that no word to with inlaws even wen once she asked me on that previous night did not sleep so hubby told she is tired n next time festival they did not wish just me which is fine since I did not wish them either even though hubby called me to spoke .
Now any time in future happens to meet or talk if they ask what should I say ..
