I think this is done to bring to the fore ishita's insecurities and to trigger her desire to have her own child i may be wrong here but what i feel is its the master plan of shagun and manoj to make that happen and raman is also a part of it i know ishita is getting badly hurt but thats the whole point they want her to go through that emotional turmoil to reach at the point where she herself would want to have a child since may b being her dr manoj has discovered ishita was not very keen on having a baby and was doing it under pressure which in turn affects her physical and memtal welbeing and can be fatal to the fetus so they want ishita to desire for a child and nothing can hurt ishita more than the closeness of sharam because of baby.., if u observe we were not shown raman agreeing to surrogacy and saying yes what we directly were shown was shaggy getting admitted for the peocedure so manoj is the mastermind behind the plan hence ace of spades may be it was shanoj plan but since raman did not agree they had to include him in the plan and shagun is not actually pregnant... And thats how raman also gets redeemed to some extent...
I know i m being over optimistic but kya karu its Ishra Yaar cant give up on them... Dont throw chappals at me if it does not go as i said 😆
