If se cries, everyone would have called her fake, but she did not which means that, she is not doing anything for camera. Her emotions are very natural and on the spot, she does not plan any feeling as it comes out organically. Maybe deep down, she is feeling hurt about him going, but I know they are portraying her as selfish because they do not have the villain this season as of now.
In the promo, she said how she is single by trying to mention how she will now be playing from the singles team.She did not even intend to say about her relationship with Anup Ji as it was misinterpreted by the channel. They always want to show one woman every season as negative, but I think there are more evil people than Jasleen inside the house.
