read lots of good point on the forum, that she didn't mean her heart but her trust was broken...and also the fact that its all pent up emotions, which she can't share with anyone but him...but at the same time...we have to remember how he tortured her after hearing her engagement news...everytime he was just reminding her that her fiance wasn't rich enough...that he couldn't afford things which Arnav easily can...
in such a situation...if she tells him that she broke the engagement, then he might feel that she did that cause her fiance wasn't rich enough...and therefore confirming in his mind that she is a gold digger
so as of now, its good that he thinks the guy broke the engagement...its ok, if she doesn't give too much details about what actually happened...
he might even get over the fact that maybe she loved the guy...cause the guy isn't in her life anymore...so that won't stop Arnav from confessing, if he wants to...
but...
in future when he comes to know that her fiance was Shyam...then...all hell will break loose.
so i think telling him anything is like a two sided sword, she won't know which side hurt her the most...
would love to hear your point of views...
