Actually its good whenever it comes out....it will be like taking off band aid...
Even with half truth & thinking that she's not told him the truth & the angst associated with that....he will still not continue in this misconception about three men and a baby
Also, he will definitely wonder about who is real mother of the kid & why Preesha is raising him. No brainer.
He also cannot call her gold digger etc because he knows now she will do anything for that kid so...
But it should also be a no brainer for Preesha to tell him about Mahima but wonder what khichdi they will make this time to explain why she, yet again, doesn't tell him who is real mom of Saaransh.
Of course this first has to be an authentic source & not just guesswork 🤣
