I was in a relationship with a girl and after four years she says that she can't marry me against her parents wishes. My life has come to an end. What do I do?

It is a really sad that someone you love so much let's you down. It is very painful but why would you say your life has come to an end? Surely the girl didn't love you as much and as truly as you did her because after four years of a relationship she suddenly realised her parents wouldn't allow it!! what a lame excuse for breaking up. Move on now. The sooner the better.I'm sure there is someone better out there for you.Cheer up :)
