Hi, you can file a divorce petition on the ground of cruelty or harassment but you have to prove your allegations so then only you can succeed in the court but your allegation is she is suffering from Hypo Thyroid and it is curable diseases and if your wife suffering from any diseases which is not curable then only you are entitled for divorce and present scenario is not like that.
2. It is the duty of the husband to maintain his wife so you have to pay the maintenance to your wife and quantum may be differ and suppose if your wife is earning then quantum of maintenance may be reduced to certain extent.
3. Since the your marriage is not completed with in one year both of you can't file a divorce before the court.
4. It is my advice is tried to settle the matter amicably and file the divorce by way of mutual consent after negotiation with your wife in respect of permanent alimony.
