Brother, I do not have time, or the will, to talk to people (Not even to those who I love and can die for). Spending time on activities that do not have meaningful benefit, even if it involves money, is not time well spent. Hence, let me explain something to u without wasting ur time any further: when a woman applies for divorce, the chances r that she has already separated herself emotionally from u. So pls give her on paper what she already has in mind.
About filing the adultry case: I’m from a farming state and there is a saying in my state, “in order to slow him down, if u try to deceive a runner into racing against u in a plowed field, the plowed field will be equally disadvantageous to u both”. So the other side may have the arsenal to file cases against u as well. Just give her the divorce without paying her alimony.
“Sometimes the best way to fight is not to be at the scene where the fight is going to take place. The one who knows when to fight, and when not to fight, will gain.”
-Paraphrasing from the Art of War
Move on and try to see, or find, the beauty in life. This may have been a blessing in disguise for u as I’m guessing u do not have any children who she has taken away: I would not have any words or advice to console u if u had children. So feel blessed and move on.
