My take on your case: I dont think you are a thief or a thug or a politician who has no shame. Its really a shame to surrender in court. Dont do that. Instead, get bail and till then be underground, just do not be in the address which has been mentioned in court in the 498a case. Be in the next door, thats fine, but dont get caught, and moresoever dont surrender. Surrendering before the court means lot of humiliation and your wife will laugh at you in full public view.
If you want to pursue the case then do it after you get bail.
No doubt your wife and her company are money minded, but there is no use pursuing the case. It only means losing precious years. It really wont amount to putting your sword before her feet, but why dont you negotiate and bargain for a price for your freedom? Like that you will be saving a lot of energy, and more importanttly time [6-7 years].
