Its a fact that if you keep aside the utter psychoness, Romi has observed Sahiba and noticed little things about her way more closely than the man who has been living with her as husband and claims to love her.
Its a shame that instead of Angad getting a taste of his medicine with what he has put Sahiba through with his lack of boundaries with ex fiance/almost wife clinging to him- he hasn't felt that pain.. sahiba is good at drawing boundaries. It'd been good tit for tat if Angad felt the pain of seeing your wife letting another male "friend" speak for her, get close to her. But she's not that crass to not know where to draw a line.
Sahiba is petrified by this sanki aashiq whereas Angad enjoys the attention of Seerat and reciprocates by letting her speak for him, and get involved in intimate things like picking out his clothes, his room decor, going as his +1, sitting in car front seat etc etc all when he clearly knows his wife is extremely upset by it.
