Please Suggest What Should I Do ?

You would surely be knowing the reasons why your wife does not want to live with you. What were the issues involved? It is surprising when you say she went with the baby promising to return soon and just stayed away for more than 1.5 years. If you are not at fault at all here, your clear option is to get hold of a very good advocate proceed with divorce. You can insist on no compensation to be paid etc if the fault is entirely hers and you have proof of the same.

 

Lawyers would usually give you a first meeting for free. Meet a few, describe your case, ask all your queestions, listen very carefully to what they say, take notes etc..., and learn. And then decide your best course with the chosen legal representative.
Divorce is not the end of the world. You have already had one for a year and a half, and managed your life.
