Relations don't work that way. That kinda relation is just a attraction according to Western culture. But I understand for Nepalese coming from that culture. In order to have a legit relation, u have to deal with her once in a while. For instances if u n her working in a same place, go to same  college etc where both started finding out similarities n differences. Just seeing her pic on facebook? Dude you can like Jenifer Love Hewitt on facebook but u can't imagine her being ur girl fren. It's infatuation. I liked some Nepali model so much that I added on facebook but now she is engaged n ready to marry some other dude. We talked on facebook but professionally like talks about her shows, her funding programs. For a instant I thought I met the most beautiful girl in this wirld. U know. Definitely she might have fall in love with me if I was dealing with her occasionally rather than chatting on facebook. I ve seen 3 of people I know, getting married who met on facebook though. It's a try, give a shot boy u never know. After 1-2 talk ask her number don't wait. Start talking on phone n then meet her occasionally. Recently i met some girl from Nepal on facebook. She calls me on skype everyday. She called me today  when I was sleeping, i got pissed n closed the laptop as i hate being disturbed while sleeping. I sometimes talk with her because I like to keep girls as "what if my wife leaves" n it's a time pass. Had I have that model as my gf I would have never hit or flirt with any chick. You will be a great experienced loverboy too talking with ladies.
