Billo kept on telling Moni that she is staying with her daughter at her daughter's in-laws and along with Billo Jeet's bhua ji kept on insulting her too by saying that how Moni never brings anything for her daughters' in-laws, i.e. always empty hand, no money or gifts, etc. Moni was very upset about it but didn't tell anyone. So both Soni and Mahi thought that if their mother lives with both of them (6 months with Soni and 6 months with Mahi), maybe everything would be fine. When Jeet's bhua ji found out about this plan, she called Billo and told her that she has to stop Moni from coming here. Billo agian went to Moni and told her now she's going to live with her second daughter etc. etc. etc., insulted her more. Moni couldn't take it anymore and decided to build a Maayka for her daughters and that's why she left the house. Hope that answers your question.
