That's an interesting question; however, the answer to that question is not as apparent or straightforward. I can entirely see how you can fall in love with someone you've never met. If you are friends with someone on the Internet and chat with them on messenger programs, for example, you would know what I am talking about. Although, I haven't fallen in love with anyone personally, I have felt connected in some ways to people whom I have never met.

People generally get attracted to each other based on common ideas, common outlook towards life, common value systems, similar views on important issues. If you happen to know someone over the Internet, you can sometimes feel connected to other folks if your views match theirs. Also, you might like their sense of humor - that does come through no matter what the medium - speech or chat text. So, face-to-face contact isn't as essential in knowing the other person. Consequently, I would think you could theoretically fall in love with someone you've never met in person.

Assuming that a couple has met over the Internet or over the phone, the more interesting thing that I'd like to know would be - what would be their reaction when they do in fact meet in person for the first time. You may like their thoughts/views on various subjects and like the online person you've met, but what if the person turns out to be, well, not as attractive physically when you first meet them. Can you overlook that fact and love them the same way as you did before you met?

Even though most people say (to be politically correct than anything else) that outward beauty doesn't matter to them, generally most people value beauty in a potential partner. So, while it is possible that you can fall in love with someone you've never met in person, it is not as possible to predict whether you would in fact remain in love with that person - once you've met them - especially if that person turns out to be not as attractive (based on your standards of attractiveness).

Also, when you do in fact meet a person face-to-face, you may discover many things about him/her that you hadn't quite anticipated. Perhaps, he/she has some embarassing habits that you hadn't quite anticipated -- or perhaps he/she has some irritating quality that wasn't apparent to you before through his/her online persona. So, while you can fall in love with someone you've never met, whether you stay in love with that person is quite another matter.
