That example was used to show Raman's instant reaction to losing the custody - similar to what Ishita's is today!! Being in love with Raman would never supercede Ishita's love for Ruhi - that is the fact and will remain so even if they remain married for next 50 years!If Ishita was to ever chose Raman over Ruhi, then her love, her desire to be mother, her reason to marry a a man she hated to be with her daughter, would also be questioned by this very forum! There is no win-win!
That's got everything to do with LOVE. A married person with so much love for his/her spouse will never say his/her marriage is meaningless without their child. "Ruhi hai toh hun mai...Ruhi nahi toh humara rishte nahi hai"...seriously?! After all this progression, she is still stuck with this condition !! An instant reaction ...huh! In no way an instant reaction can chuck out your relationship with your spouse! Is it that easy when you claim to love him/her! Then it's not love in the first place.
And, her reaction is not so Instant. She will elope with Ruhi leaving everyone.
What is she thinking?! She will run away and settle down somewhere else with Ruhi?! If so, he's punishing Raman and every other family members with her selfish deed.If it's not the case, then she has to comeback someday. What will she do then? Ishita's obsession for Ruhi isn't helping anyone.
Ruhi can always be her first priority but not the SOLE priority. Just for the sake of Ruhi, she can't discard every other relationships. It's not healthy, it's madness. If she can discard her marriage like that, people will definitely raise questions.
