From what I understood, Aditya made it very plain in a cold heartless unsympathetic manner that Malini was not his wife and that he was already married in a village ceremony prior to their (Malini & his) marriage. Btw, I did not see any regret or empathy and pain in his eyes or manner. He was very much matter-of-fact.
So there is no need for a divorce lawyer. Malini should pack up her bags and leave ASAP. The sooner she leaves that utterly despicable man and his teenage squeeze, the better for Malini to begin to heal. She is in shock right now, then there will be self-pity, then anger, and ultimately, revenge. I want to get to revenge as quickly as possible.
Also, just to clarify Malini and Aditya have been having sex for the last 7 years and 5 months! š š¤£
That's what "being in a relationship" actually means. I don't want to corrupt the sweet young minds on this forum. (bless your hearts) But in Indian serials, some things are implied, not actually stated.
Also, young people in 20s and early 30s pretty much are shagging all the time. Malini and Aditya met at college. I can assure you they were not "studying" all the time. š¤£
