I am 23. I live in abroad for my studies. Since I have gone there, I use to chat regularly on orkut, yahoo etc. 18 months back I met a girl online who is from India. Soon we started loving each other. Now at the moment, I can't live without her. We haven't meet each other personally but still, I am totally lost in her love.
The problem is, we both come from different cast, she is Rajasthani. Now her family is very conservative and inter-caste are not at all allowed. So, the girl is scared and she is not able to tell anything to her family and is trying to forget everything. As said by our common friend who is her college friend, she is very much upset with the situation but still not agree to face her family. She is just showing me that she'z happy.
I want to ask you one thing. Her brother is in the same country where I study. So, Should I go to him and tell him everything? Isn't it a betrayal to her? As there is no other way I can see from this point.

why don't u discuss with her first and then inform about it to her brother. this way if there is any risk of getting punched by her brother will be reduced s she will inform u before hand. and caste is not a big deal. all it matters is how much u love her. if u give her time n if she really loves u then surely one day she will talk to her parents regarding your relationship. btw PYAR KIYA TO DARNA KYA??

all the best and if baat banti hai toh inform me, ok!!!!
