If you really feel and believe that worth her to call back then foloow the below steps. If you feel its not going to work, then better appoint a cook.
Let me tell you the steps,
Step: 1 (Very decent approcah, good for your wife and your last chance for her)
Talk to her openly and tell your concerns.if its not working engage elders in the family and society and bring to common people knowledge about her acts. Dont feel bad, otherwise it wont help you in life anyway. Involve 3rd party in the discussion (Some people only relaise if society watching their mistakes). Dont keep it everything in you and bring out.
Step:2 (Little medicine)
File a restituion of conjugal rights and in this petition strongly mention that you need your wife back and send the court notice. also please mention that whatever she demands from and always staying with maternal house no in marital house. this is very much required, dont feel bad for going court. itsa best solution.
If step 1 & Step 2 not working then apply for divorce immediately find a good partner
