Kailash- I thnk he had sum reason 2 break the relation with Preety...may be he was forced 2 get married 2 another girl 2 clear his debts...and he was weak person so that he accept Preety...
Now as per article he is a reformed man and has got a troubled married life...so chances are der 2 clear MU's between Preety-Kailash so that they be together again and may be PaYa will help
