I don't think Ovi was ever wronged. What she is now is what she has always been. She never realized that Arjun never loved her even when they were in Canada. She was the one who always claimed to love him to the point of obsession (the reason I use that word is bcos they always showed Teju thinking that way).
In Canada in one of the parties, it is she who falsely tells that Arjun is her fiancee and later tries to get close to Romil and others in the hope that Arjun would feel jealous. Arjun comes to her rescue when she gets into trouble with those guys, but Arjun did not help bcos he loved her, he helped her bcos she was in trouble and she was his friend. She mistakes it for his love. Later Arjun tells both parents that he doesn't love her the way they think he does but is willing to marry her with the thought that someday the friendship can turn into love, since he is always busy and isn't really looking for love and would accept anything that Ovi can give him. He never had planned to fall in love with Purvi but it happened.
After knowing the truth about Arjun, if Ovi had given up, instead of claiming that Arjun did not love Purvi even after repeatedly telling so, and making herself and her family miserable, I would have respected her. But no, she wanted to achieve him and nothing else. She did a terrible mistake by marrying a man knowingly well that he loves someone else. Which was completely wrong.
When she got what she wanted, she should have made the best of it, but no, instead of that, she kept blaming Purvi. Arjun and Purvi never planned to meet or talk after his marriage, but they happen to. If Ovi could give up on her mistrust and insecurities, she could still make a good life, but no, she has never known what those are. If she did, she wouldn't have married Arjun.
Even after loving Purvi and bcos of Ovi's mistake if Arjun married Ovi and then if Arjun had realized he did infact love Ovi, then that would have been a different story. But Ovi is not making that happen, she is hell bent on blaming Purvi and destroying her married life. In addition she wants to trust Punni. If such is the case, no one can help Ovi. She needs to fall, only then she will learn.
