I want to congratulate you for getting the quash. Go celebrate it. Why do you still afraid of this becoming public ? Please dont take my advice negatively, come out in public and share your story boldly in your friend circle, office.
498A is a very serious and notorious law in India, and the worst part it is easily misused and played by wives. But you know what, things are changing.. more and more men are coming forward to fight it off boldly, and the litigation is made a mockery by the husbands rather than the wives, as it should be. I am immensely benefitted by the support and materials givrn in LCI, various men's right orgs, and one husband who won a historic case. I also want to give back to the fraternity, not just walk away with my personal win. I wont advise you to do it, but do think about it.
