You will have to figure out as to what is that  you want out of your marriage at this stage. In case you wish to stay with your wife, then we suggest you to go to a marriage counselor and try to give your marriage another chances.

b. has deserted the petitioner for a continuous period of not less than two years immediately preceding the presentation of the petition; or

ii. has ceased to be a Hindu by conversion to another religion; or

iii. has been incurably of unsound mind, or has been suffering continuously or intermittently from mental disorder of such a kind and to such an extent that the petitioner cannot reasonably be expected to live with the respondent.
