Why Mathura

Why Mathura is making Rusty sit at home. If she would have asked Ajeets' Rishta for Rusty, She could have get rid of her pretty fast......As Rusty will start living with Ajeet in lovely Canada :)....but she is one dumbo joh apne pairon per aap hi kulhadi maar rehi hai by pushing Andy to marry Ajeet....kya uska erada hai Rusty ko umar bhar ghar bhidhane ka ?

She knows that Rusty is in love with Ajeet and so she wants to torture her by
doing all this...

yah she knows the only thing keeping there is ajit, n if he ends up being someone elses then she wont have a reason to stay nemore :(
