Victory is won not in miles but in inches. Win a little now, hold your ground, and later, win a little more.
Your two years of patience had made them to come under the table for settlement inspite of the stages which are on trials.
Now, the ball is in your court you have the upper hands, how you serve the ball.
A/t your statements she is having a salary of 45000 k with no child, the marriage durations are not too long.
That means, she has the chances of remarriage which is the most crucial point in deciding the final alimony if any.
So, in your case you have two positive points to be considered for no alimony or very less alimony.
As per sec 25 hma sub sec 1 and 2 , you are at upper hand and the chances to get even 4 lakhs to her is very bleak.
In my oppinion if she agrees for 4 lakhs according to your wish then go for that or else i dont think 2 more years will cost you 6 lakhs if she again comes under the table at your terms.
Ps: U/s 25 hma it is the wish of the spouse to pay as monthly maintenance or give final alimony. So, if you choose monthly maintenance but then also she cant get that because she is earning equivallentaly more than her maintenance. So stay cool if you are not in hurry and fight for the reason that she is an unscrupulous woman who wanted to extort you but you havent succumbed.
My best wishes are with you))
