Now, my prediction:
I really want the cvs to use the Europe adventure here. I assume that after tomorrows episode and the promo scene Raman will assume that Ishita loves Mani and not him which make him think that she is cheating on him. Also, he will understand her reason to do so because she never found that love from him. He will start to distant himself from Ishita and will create more misunderstanding btw themselves so, that he can stay away from her. Even thought, Ishita will feel that Raman is changed, she will be busy trying to solve the issue and ignoring Raman problem which will be her biggest mistake because seeing this Raman will understand that even she doesn't like staying with him so, he will apply for divorce because he will do it out of love for Ishita to see her happy. Then, after Ishita ill successful in her mission, Raman will hand divorce papers and they will fight more. This will lead to Ishita confession her love to raman in front everyone, and shocking Raman. However, she will sign the divorces papers and leave Raman. Next, we will see how Mani will make Raman understand of his mistake and make him try to convince Ishita, but he will too late. (Next part I hope will happen) Ishita in order to keep away will go to Europe to work there and spend her time helping people or something like that. Raman will go mission to bring his wife back home and make her his. This will the process that will begin their to their journey mohabbatein.
