Pawan , I think you should be more practical and positive. It is because if you are thinking negatively and wants to end everything if she is not with you then you are closing all doors to your solution.

My first suggestion is to think positive, I am sure there will be a way.

Second is that since you have asked her an year then why don't you work on your career, make it so bright that her parents get dazzled from it and can't say no after that. I know all parents want a good husband for their daughters, I am sure if a very successful person comes to their home and ask for their daughter to marry, there are almost 100% chances they will don't deny.

So, instead of wasting time, plan something to make it big.

May God Bless You.
