hmm . but this is a catch twenty suiation na . if u go to meet ur ex that too in a hotel room. baat toh udti gyi na . be it anyone. will aradhana not have asked if the role was reversed.
But he did not ask na, he directly blamed her but that doesn't make her lieing to him correct and I guess when the forgives track comes and she finally agrees to forgive him they will take this in consideration and she herself accepts it or maybe she throws many tantrums, like more than needed types, and Rey gets frustrated and he might say this on her face that this all started with your lie. I just hope that it's the first case scenario because these ITV people don't really understand the value of words and if Rey confronts her with this they will definitely mess up the dialogue which will again get him Galis!
