yes it was Meethi's mistake and she needs to realize what she did by breaking akash's promise. Meethi also had to realize that she needs to put her, akash and baby first and not give first preference to others.
Ichaa also lost everything giving preference to tapasya. Everytime she put tapasya first and veer behind...now meethi's turn. I hope akash does not forgive meethi for sometime for what she did by putting baby at risk.
there were lot of people whom rathod could have taken...taps, police, jogi, akash etc...whatever the reason he took meethi is not justified at the cost of losing baby.
