I’m going to be blunt — he would STILL keep you a secret if you were white. This relationship will not go anywhere and you may end up spending years of your life in a  situation in which you will feel nothing but heartbreak in the end.

As someone (white) who was involved with an Indian man for two years, and listened to his constant proclamations of love and asking me to marry him, when the time came, he told me it would never happen because his parents want him to marry a virgin Hindu girl from the same caste. There was no negotiation. My feelings and what we shared meant nothing in the end. He got married two months after this conversation to someone that was more palatable to his parents and their society.

Please do yourself a favour and read more on dating Indian men in an interracial relationship. There are patterns to this. No story is unique but they all have a similar thread running through them. Here is a good starting page:

Indian culture is nothing like ours and needs to be studied a bit before deciding to get involved in it. Trust me, I wish I had done this.
