First my appreciation not filing 498a because that itself loosening ground for marriage. proceed to initiate with RCR , if he does not trun up then it is his fault, and get exparte-decree and go ahead with your divorce process. If you are real victim , then after divorce file for maintenance. Please remeber life is important than dragging the life in courts.
Why i tell you not to file 498a.
1) At some point of time, you will be tried convinced by bad lawyer ( learned good lawyers kindly pardon me for such words) that its is the fast way to get divorce with fat alimony, which is not true , because he cn take same as advantage to fight in court even if he is faultier for other reasons.
2) tagged with 498a , possibilty for second marriage is in doldrums
3) RCR first, if he does not turn up exparte-decree, by then when separation is two years of time, divorce pettition.
4) never use any criminal sections, it only makes your life more miserable
Please consult a lwayer who is not pulling you to 498a
All the best, hope you get good partner in second time. many times success comes at second time in life
