if her brother is not in the picture there must be a reason for that i think its to do with what he did to kinjal n modis
also nileshs father said he said before that he did not know that anita had another relationship so when was that mentioned or was it that they knew she was in another relationship it was just a excuse my take is that the family did not want nilesh getting married because anita had no family its a taboo they wanted someone from a khandhan family not a anath my take, they did not trust her.
i feel that nilesh n his family dont deserve anita
