Ishita has accepted Raman the way he is with his flaws, his anger, his family, his past and all his insecurities then why leave her now when she has gone through the worst for him with no complaints. In fact, if it's anyone it is her who can bring peace and semblance in his life. Agreed he loves her and loving her doesn't mean that he has to keep her away from him so she does not face these issues. If not this then she might face another set of issues. When he breaks his relationship with Ishita worst things might happen to her considering she has gone through this same level of rejection and emotional turmoil more than once in her life. It will be a blow to her self esteem where she might not recover herself fully since she has fallen in love with Raman and went above and beyond for him and his family with no qualms. In the name of sacrifice, Raman is going to make both of their lives miserable without thinking through and understanding the ramifications of what this might do to Ruhi to whom Ishita is her world and cannot imagine a life without her. How will he be able to explain Ruhi?
My hope is that Ishita catches on quickly that Raman is acting indifferent simply because he does not want her to suffer because of him and blames himself for all her issues. I want Ishita to smack some sense into him and tell him that she is his wife and is more than fine going through all the trials and tribulations with him. If this leads to separation and in turn they realize each other's worth in their life leading to a heartfelt confession then that is fine with me. In the meantime, my worry is Shagun driving a wedge between Raman and Ishita considering that they have just realized their feelings for each other and have not yet admitted to each other. Raman is completely over Shagun and hence I have no worries that he would ever get back with her even if circumstances force him to be with Shagun. He is madly in love with Ishita and would do anything to keep her safe. So, I don't think he would ever get back with Shagun and if ever that happens then viewers including myself would bid good bye to this show. I am sure EK will use all the twists and turns to rake in the TRPs but at the end of the day the USP of the show is Raman and Ishita's love story and if that gets jeopardized of course the show will go on but not with any viewers.
