How did Mohan isolate Selvi from her mother?

 In her childhood, Selvi lived with her mother in a torn-out house in Vinayak Mudali street. But when she was married to Mohan and she gained fame, Mohan bought a house name Lawley Terrace. There Selvi always remained fortified within her room. No body got the chance to visit or see her. Even Mohan did not like that her wife would meet her mother and other family members. Whenever Selvi told Mohan to visit her mother’s house, Mohan ignored her request and said that all were well. Sometimes, Mohan would suggest to send a car to bring them in their terrace. Most of the time, Mohan rejected her proposal by saying that when they would get enough time, they would visit Vinayak Mudali street. But that time never came. Selvi understood the matter and later she gave up the will to visit her mother’s house. Thus Mohan became successful to isolate Selvi from her mother, brother and sister.
