Then stay in your own home and deal with them how you want to. People will always talk regardless. If you spend your life thinking about what people say it wont get you anywhere
Like i said and the other posts aswell get your husband to help you. Freeze food so it makes life easy for you
The days your inmediate family r lver surely they can help themselves or atleast have the courtesy to not expect lavish dinners. If your bhabi is willing to help just ask her to make you one pot of salan and get naans from outside kf someone comes and u reallyfeel theneed to serve them just do that!
You keep saying youre shocked at tour own thinking of even contemplating staying there so dont do it.
Your husband supports you. Maybe look into getting a cleaner and both of you work as a team. It can be done. If your mothers friends want a full blown meal they should get your mother to treat them!
