Why can't abhimanyu just say no?

I see abhimanyu has 2 modes of decision making

1) impulsive, reckless

2) leaving the decision to someone else

There is no measured, thought out rational decision.

Everything with akshara was in supersonic speed without any of her input. Like akshara said that he never listened to her views, never talked to her, just decided

And now with arohi,, he is just the opposite where he takes no decision but let's her decide and he just goes with it. Everything with this marriage has been left to arohi/mummy ji.

Today, After everything he again leaves the ball in arohi's court... Like you know you don't love her, your exwife said that you failed as a husband, you have zero interest in marrying again then why why why would you go ahead with another marriage

Can't he just say NO. To his mother, to aroohi, to everyone and just say i need time.

If abhira is endgame, then give us a hero we can root for. Now that he fallen to rock bottom, show him rising. I adore harshad, i want to see more of him. Show something hero-ish. Show a story of redemption and second chances...

Instead yeh shaadi khinchne wali hai and then 5 mins before the pheras he will find out about abhir... Urghhh
