it is not only you we all gone through same situation, some may be more.
anyway when you or feel like, fell out of love, its waste staying together. still if any chance if there is any compromise from both sides its useless stay married.
if you are thinking divorce her and get marry again, still there is no gurantee that you will find better one…! some found wrost than 1st…..
anyway thats thier FATE.
as you asked easy way, but for us MEN in india there are no easy way out unless you are a woMEN, unless you find valid points to claim divorce or else you will Die worse fighting long legal battles.
