Om Sai Ram
Why u blame Baba, rather thank baba he saved you at the very initial stage. Seems you loved him a lot but he didn't love you. If he loved you he would not have engaged to other gal. It may be love in your sight but what baba think about this, this is only attraction and when it ends, it leads to separation.
So feel good that worst has not happened to you, Be positive and wait for a guy who love you.
Om Sai Shri Sai Jai Jai Sai
