Well, I can understand her apprehension about admitting this....perhaps she's embarassed by it or something. But I really think honesty is the best policy here......if the unfortunate happens and CIC requests an interview.....you or her (I forget which is the principal applicant) could really get in trouble if you backtrack on the story in your application of you meeting through a family member and start talking about meeting through Bharatmatrimony.....and you don't want to give CIC any reason to doubt your relationship. That's just my two cents....
I met my husband in a chatroom connected to a thing called Livestation.....where one watches channels such as Al Jazeera English. We had a lot of contact virtually before I went to meet him. Then I went to meet him a second time (months later). Then he came to my city to marry me (another few months later). So we were physically together for about 6 days total (two separate trips of 3 days each), before he came for the purposes of getting married. On paper that looks ridiculous. But it's the truth and I can only hope that CIC is convinced by the evidence I provided (plus the fact that I've been living with him in Canada for over a year now).
