they were to save babita from hurt not to hide things from her because lack of trust. About her friends she has been open. after the depression case even babita accepted mickey as minis friend and welcomed him. i remember mickey telling mini your mom is so accepting why are you scared of her
i dint say it was only babita but she was the last trigger to it. Mini did not share about manmeet because she felt babita wont trust her and blame her she was really depressed because of that too. Ironically the last time babes dint trust mini with her friends was also because rano taunted her. So its not because she herself dosent trust mini. Its because she has to listen to taunts and expects mini to toe her line because she dosent want to listen to them. Today remember when mini told you insulted me in front of my friends she retorted with even i am disrespected because of what you do. If she herself was really worried and did not trust mini or wanted to rest her doubts she would have dealt with it in a more coherent way.
I think she herself did not want to marry because of taunts she would have to face. mini to sirf bahana thi. like they way she hid behind mini in beginning of marriage. Now because of mini kammo taunted about her friendship to HS too and that made her even more angry
Regardless of the reasons, she did lie. She chooses to hide things from Babes and in the end they come back to bite her.
Babita's problem is that she not only takes other people's words to heart, but she also doesn't stand up to them. If she shuts them down, and lets them know that she won't be treated like a garbage can, then they will think twice about saying things to her.
