Been, you really are on a roll - I love this
"brutal truth is he's nothing more than the character in a book you've read. The one you think is amazing until you see the film and wonder how the hero could possibly look like that."
I do actually think that how a person behaves on text / online / in writing / on the phone is really important, and part of the relationship (relationship of whatever kind!) I have a lot of friends and family I don't see all that often and love to hear from them in other ways - I know some people are very "real life or nothing" and I'm not like that.
On the other hand - it isn't real till you've met. It is an odd thing that is true of everyone but, realistically, only really apparent in OLD dating, that - no one really looks like the photos of them. When you know someone in real life you are able to see "them" in the photos of them (or most of them! There is always the odd weird one). But it's kind of partly your memory of a living, breathing, 3D person who speaks and smiles and frowns. when you have no real life frame of reference, it's just a handful of images and they don't really mean very much. It's very odd but you never really "see" the person till you meet them. (also really interesting how your mental image clicks into a different gear when that happens)
