1. Filing MCD will be a mutually wise decision in such circumstances. If your wife does not agree to MCD then you may unilaterally file for divorce on the ground of cruelty committed by your wife. The court would give her an opportunity to rebut your case. Gone are the days when the divorce cases ran for eons.
2. Since your marriage is not a year old yet you may file for divorce on the basis that your wife's conduct is exceptionally cruel. Alternatively, you may file for judicial separation.
3. Remember that your wife may hit back by filing cases of domestic violence or assault, in which event you should contest them in the court.
