i think promo indicated that

well in today's episode dev confused geet by saying maan's happiness will be gone if she told him everything.and geet is confused to take which decision and as promo she asked maan family bonding more important or their relation and bangles broke i don't know but as this is serial nothing will go straight for sure so i don't think geet will tell maan anything coz she might ask maan indirectly how much important his family is for him and he might say something which will stop her from telling anything to maan for now after all story main age jake masala mix karna hai itini jaldi geet maan ko kaise batayegi.i think maan seeing so much emotional for family geet won't say anything about dev but will engage or not that's the question but she should otherwise maan toh waise hi pagal hogayega.but one thing is for sure the kind of person maan is when he will know about dev's crime he should sure punish him badly coz he is shown as a guy who never forgive wrong deeds and what dev did was crime earlier he punished dev for gambling and wasting money although he loved him so much then after knowing what he did to geet he will almost kill him they can't show suddenly two brothers love so much that maan will forgive dev no way.
