Regarding ragini's trust issues...like they say trust once broken is difficult to regain. And let's not forget, all of it happened too soon- ragini realised that Neil lied to help rupali and didn't clear up the misunderstanding for years, then she came to know that Neil hid about meeting rupali in US...she makes it clear to him that she likes to know the truth from him, no matter how bitter it is AND the next day Neil hides about aarav being in danger.
On top of that, things go really ugly with someone dying and aarav getting jailed.Yes, Neil meant well and yes, he apologised...but this time it is their son's life which has been severely damaged...son that was her responsibility. It isn't that easy to forgive and forget.I am not saying that ragini was never at fault...she too has made mistakes. Her speech at the court was badly worded, with her accusing him of not loving her and aarav. The fake marriage and engagement have both been blunders from her side. Add to it not meeting aarav in jail due to her lack of courage.But I still maintain that Neil should realise his mistakes( I don't think that he really thinks that he was wrong, the apology at the court was just to calm down ragini) and stop repeating the same mistake with the other kids. This is why I want ranbir, suhani and agham facing problems, so that he self-realises his follies as a father.And the moment Neil starts rectifying, I am sure he will be forgiven. This is what would break ragini this time and make her confess about her feelings.
