This is very interesting to me. I think you are right that Archu told Jaywant she was ready to move on, but what is odd to me is that i honestly thought that when Jaywant acted "so kind" to Archu the script showed him acting one way and then we were prvililged to his "thoughts" which were the opposite...like you think i'm being kind to you but you wait until...." - from the very beginning i thought it showed him with ulterior motives... otherwise,i too would have thought he was just an innocent victim.
I wonder how there can be such different remembrances of the story line....or if all of us who don't like Jaywant imagined his ulterior motives and thoughts, and those who do like him, ignored them. 😆
It might make a good study in human nature....
I think the creatives switched his character around, now he's completely evil for sure. But I think back then they were trying to show him as just a career-minded person who also would have wanted a good wife (and Archu is since she's loyal to her man but that's not him😆)
I'm trying to remember but the story has moved so forward that its just a blur. But when Dharmesh first told him about the rishta at his house, Jaywant told him that he would think about it. Then he went in his car and thought that he could say yes but he also wanted Archana's raazi as well. He thought at that point that in order for a marriage to succeed, you need both parties ready; he also thought about being a partner in that D&S company but he also thought right afterward that it wasn't worth it to put himself in a one-sided relationship where he would care for her and not her for him for the rest of their lives. That I remember specifically because in one of Kool's Commentaries, she did a comparison of that statement with Shravani (i think?) who wanted Manav to be only hers regardless if he loved her or not. Jaywant, after Archana proposed to him, tried to transition himself and her in this new relationship but drama after drama happened concerning Manav until Jaywant couldn't take it knowing that he had started to care for her somewhat but she was still fixated on her ex. So now he's going to ruin her and still try to get the company because she messed up his life (unconsciously I think) when she didn't have to.
So in the beginning, he was pretty patient and understanding, but somewhere along the way he went over to the dark side!
