I also do not think she has deep feelings for Angad otherwise she would have married him. She wanted some sort of affection and the Brar name which she hoped to have with Garry. She is seeing this with Sahiba and she is super envious, This is just making her second guess her choice. At this point, it will become obsession with Angad, she is just selfish, shameless, and ratchet. Her and Garry was a match made in heaven and even he saw her as his hell, go figure.
