I totally agree that Harleen's demand is unreasonable and also feel that Mehar SHOULD NOT give in to her demand. But leaving is not the option. She along with Sarab should try to make her understand. Had Harleen been bad or wrong, she would have never supported Mehere on many occasion esp in front of Dolly Momsy, never gave her keys of household and lockers to her. If we think from her POV, Harleen is not wrong either. Intentionally or unintentionally Meher and her family cheated Gills. Yes Meher told Sarab on the first night after wedding but don't you think, it was too late to reveal her secrets. I agree Meher was a great mother to Param but what Sarab had paid or was ready to pay for it, was too much to ask for. No I m not talking about Sarab giving his name to Meher's upcoming baby. I m talking about whatever happened in Serbia. And first thing which I strongly believe Meher should do to tell about her mother's brutality and scheming mind to her husband. Plus considering Harleen's fear Meher and Sarba together should try to pacify her, esp Sarab. he should make her believe that he is her same brother as he was always.
I am dreading the day when Harleen would get to know about her husband's bad deeds. She will definitely be shattered but does that lessen the bad deeds of Dhillons esp Kulwant Kaur Dhillon.
