<human>: Can you condense the text into a few key points?

Hi,

So we're both 20, going out for 4 months now long-distance/never-met - and I've seen photos of her - but I still, after all this time, don't really quite know what she looks like, fully (from head to toe). I want to know, because I want to make sure I haven't fallen for my imagination of her rather than her as a person.

From the photos and the webcams we've done, I've definitely been attracted to her - she's very pretty. And I don't want to say things in a way that will hurt her, nor do I want her to be with me if I HAVE fallen for my imagination, rather than her - it's obviously not fair on her. I've seen photos of her via mutual friends on Facebook, and whilst they were a long time (over three years) ago, she definitely looks different to what I thought - still pretty, but I think it's obviously important to know her for who she is, not who I thought she was. I was thinking about saying something to do with how exciting it'll be when we first meet (which will be in mid-summer, some time), and I want to make those imaginations reality. I've re-worded the text several times and it still sounds like it could be misconstrued.
<bot>: Still don't know quite what my long-distance/nevermet GF looks like, fully - how to broach the subject?
