Nadini marries Ansh, but she is not happy with him. she know now that Ansh is not a good guy and he was just pretending to be a good guy so he can maary her. She told Tulsi this, but Tulsi didn't believe her. Tulsi also kicked Karan out of the house because she saw Karan and Nadini at a hotel. That's was one of Ansg's trick. Hope this helps๐
