Frustrated with MIL Koki!

What kind of mother in law is Koki! She is jealous of her son's relationship with his wife! I have seen alot of serials and alot of tracks but this is brand new! To be jealous that her daughter in law and son are getting close and not paying attention to her. Does she not want grandchildren, does she not want them to have their own life! This is so beyond me! Instead of being happy that they are finally happy with her descision to get them married in the first place. She is upset that why are they happy! Ughh so beyond frustrated!!!!!
