All I see here are three families that are going through immense trauma. May God usher some senses on them and allow each of them to live in peace.
At each step, we see injustice being meted on the guy(Rohan) and lady complicating matter even more... all for the vested interests of the families/society and parents involved.
All parties involved are equally responsible for this mess. I would hold the mother of the girl as the most responsible. If she had nurtured a friendly relation with her daughter she should atleast helped her take an informed and mature decision, or atleast stop a meaningless marriage. The lady is also responsible… once you are in a relation, it should be all about discipline and self restrain.. she should have acted mature and acted per her mind… not heart. And the guy(Rohan)… why he intruded in the married life of a couple. He should have distanced himself and should have instead helped the lady lead a fruitful married life. Things should have corrected itself over time.
How to solve? What is the way out? Very difficult to solve.
Doing some mathematics... there are three parties involved here; The Guy, Husband and the lady. If husband divorces the lady, then the other two parties can “probably” live in peace. The husband can continue to be their best friends and mentor. There is no way he can win over a "wife that has already eloped" and should resign to his fate. Things are already out of his hand. He(the husband), should consult a counsellor and psychiatrist and take necessary medications(anti depressant etc.) so that he can ride through this episode. No doubt this will be a tough decision for him as well…. But eventually things will heal and he should be able to remarry.
At last, I see that there are too much emotions involved here. There is no guarantee that these emotions will not turn against them (lady and the guy). After the dust settles down and the guy receives the lady, will they be happy throughout their life. That is the big question.
Anyway I wish all of them best of luck.
