Earlier someone in the thread had mentioned the point regarding Adi's reluctance to reveal the truth about his marriage to Imlie to anyone because that would mean separation from Imlie. I think there is 100% truth to this point.
When the forced marriage was fresh, Adi was angry & refused to acknowledge the truth of the marriage. But he was still ready to come clean. He planned to reveal the truth to Malini & then his family. However after Malini fainted & realising her fragile state, he was afraid to reveal the truth.
After that he tried his hardest to make Imlie leave his home. But someway or the other his family wouldn't let her leave. Finally he himself went with Imlie to PD to leave her & made up his mind to reveal all his kaand to SK. But once again was stopped by Imlie who feared for his life.
Parallely to this, Imlie slowly started to become his focus because she was naive & had a habit of getting herself into trouble. His protectiveness for her continued to increase even though he distanced himself from Imlie with anger & accusations. But he still wanted to be loyal to his commitment to Malini & managed to leave Imlie in PD. But then came the monumental gunshot incident.
The gunshot incident where he realised that Imlie could actually die broke down all his walls. There was an outpour of all his suppressed emotions for Imlie. When he was trying to hold onto Imlie to anchor her , he emotionally also bound his life with hers in some fundamental way.
We can then see how any mention of revealing their truth on their own stopped from Adi's side. He actively tried to prevent the truth from being revealed. I do not remember any incident except for the vague statement by Adi to Nishant about him revealing his secret when the chances of people being hurt would be reduced. If there are other incidents apart from this then let me know. But I think that was the last time that Adi actively spoke about revealing the truth.
All his discussions with Imlie have then revolved around how truth cannot be hidden & will be revealed on its own. But he didn't bring up revealing the truth by themselves post the gunshot incident. This was because he had somehow accepted Imlie as a part of his life. We then saw how his comfort with her began to increase, his protective gestures started to increase. He actively started to show his worry for her well being though most of the times disguised in scolding. No one can forget the bridge rescue incident. Anytime Imlie was not in his radar he would become restless.
Basically he didn't want to reveal the truth post gunshot because that would mean separation from Imlie. As soon as he reveals the truth to anyone, the only rational advice he is going to get is to break off his relationship with Imlie. But now Adi cannot live without Imlie. So it is a delicious conundrum.
The story is really structured so well. The entire journey of Adi- Imlie relationship is so well charted. But both Adi & Imlie are going to have to face the consequences for their actions if they want to be together. That's the price they will have to pay if they want their happily ever after.
