His dad , step mom and Aman knows that he has been scarred by his mom leaving him
I don't think his younger siblings realise it
Ritwik had started trusting palak and told her about it then came the Samar mishap though palak was incidental in the crime but Ricky blamed her because she showed her loyalty to somebody else .. he wants to be the alpha in his woman's life .. he asked her mera Kya meri behan ka kya
He wanted to hurt palak by telling her about his engagement she congratulated him he again got angry and created a mess on Rohit Setu engagement
After his MU got cleared somehow in his desperation he got back palak
Though he did not want to acknowledge it
When palak refused to leave him in the mercy of kidnappers I won't leave u did u get it
He gave back the trust to her .. the unconditional love
Ritwik dependency on palak will make him break the wedding
Before the wedding palak will say I am going to Mumbai or somewhere else
It will be the same sense of abandonment he felt when his mom left him he will panic and break off the wedding midway to stop her
That is the only logical stop to the wedding
If Ritwik does not confess he loves palak it will be his inability to survive without her will make him do it
