May be she is expecting that Fateh will get a job in Canada and divorce Tejo then marry her and take her to Canada.
If he doesn’t get Job:
He can never move on and die every day in her memories, she can marry some Canada guy and go away. But Fateh has to suffer and live miserable life.
Is she doesn’t get any Canada Guy:
She can make him divorce Tejo and marry him...
Anyway she is selfish, just thinks about her happiness. She doesn’t even care for her Sister. Trying to intimidate Fateh and not giving him space to move on will destroy both Fateh and Tejo lives the only people who gave up their dreams to fulfill her dreams.
