I dont think marriage is A road-Block here for prerna to accept her love with Anurag...Her family is in her support, she will obviously get support from Maloy and Anu if she wants to break the marriage and more over the girl feels creepy around Navin, may be she is still sticking only because of the reason of Money...in reality this is not logical considering she is educated, she can discuss this with Family and ofcourse all can work hard and repay the Loan apart from marrying Navin...
I believe what is holding them back is their own feelings...till date they were seeing each other as friends and in recent past many events have effected them to make them realize they are more than friends...though they understand this they are rejecting and denying their own feelings going on path of friendship 🥱The sole reason why they dont want to accept might be this reason as both of them are worried about what the other person will think if they get to know each other's feelings...what if they loose other person due to this new found feelings...what if they loose their friendship of these many years because of the beautiful feelings that is getting groomed at present...They both respect each other and they need each other in life...so I see the only reason for them from denying the truth is the fact that they are scared to loose each other's friendship if they confess their feelingsI may be wrong but this is my Take on the denial of feelings
