True love doesn't happen right away; it's an ever-growing process. It develops after you've gone through many ups and downs, when you've suffered together, cried together, laughed together.
-Ricardo Montalban
In my view Omkaara got some inner feelings with Gouri . But Gouri seemed like a bad girl in his sight earlier. Even though he could take the decision beyond the limit (marriage) to save her.
He would have never done the same thing if the ugliest girl were in that place of Gouri.
Now he is in confused state. His heart wants Gouri's closeness but his mind recalls the previous incidents often to reject her.
Love is just a feeling and it never comes after the certificate verification. It may disappear sometimes for somethings but it will stay in our inner mind until our death if it is true love.
