Divorce decree is just one piece of paper which you might get at the end of a divorce case. The way it looks you wont get divorce even if you file it today or a year later. You should have filed RCR case on her 2 months back asking her to come back, failing which you will be forced to go ahead with filing divorce petition. If you file divorce petition now, and she contests it, it will be a good decade that the case will get over, she will file a host of cases on you including alimony, for her and the kid, which you will have to pay. I don’t see any ground for divorce which court might be satisfied with and grant you divorce.
If you want divorce,
a. File MCD, you get it in 6 months time.
If you don’t want to roam to court and she wont agree for MCD, you simply stay put, enjoy life, but file RCR now. That will take care of all the cases which she may file against your bunch. Don’t bother too much regarding divorce or she going and sitting at her pa’s house or the kid that she took her with, don’t bother about the NCR also. IF you have loads of money then buy divorce decree via MCD or else stay put.
