Well this is your life and every decision made by you has a consequence.
You ftoped the life of wife in Nepal. So you made a huge mistake.....Now if you think you want to correct that mistake by leaving a baby without  father then its another mistake!

If your baby mama treats you right and wants to enjoy Nepalese way of culture then work for it....if not......

remember "Dui joi ko poi kuna basi roi" there is no right answer! Prolly go to your wife!
