Firstly , i think something has happened after bh's comeback from muth .I don't know if bh told some story or a little bit truth or whatever but sthing has happened ,kanha's such talks indicating this a little and more dev's tone.I have seen precap many times to analyze his tone and its feeling like he has broken down like he has faced sthing bad .
I know he made sin and last decision was his only but radhika made him see this point .If radhika would have with him,he would have never done this.He has only 2 persons who he thinks of first dadaji and then radhika as he said.When both left him in giving company ,he felt alone and his character is like to choose easy way always in such situation.When radhika is with him,she gives him strength much needed and makes him feel like nothing has happened always and so he face situations but without her,he can't even think of.
What i am scared of is ,how he will react when he will come to know accident of radhika and in grave ...i am not able to even think of dev's reaction.When dadaji were dead due to heart accident ,he became dumb down and when he will come to know radhika's such situation and reason only him.how he will feel...the only person he has in his life he thinks of him ,on the verge of leaving forever...
I want his radhika our radhika to be near him at that point ,kanha can remove sadness,remove worries but the burden he will have under ,soothe his pain ...its only his radhika as his heart will feel peacefull only when it will have his soulmate near him owise with his mind ,his heart will also feel pain.
P.S.: Between ,i am not against radhika .Radhika did what she felt right. she was thinking herself the reason of dadaji's death ,yes it was dadaji's fear of facing truth but reason ,she became and after this coming out of truth,if RP would have snatched from them ,would she have able to forgive herself and she gave promise even to dadaji to keep safe RP.
