|I think you can fall in love just by talking - but there are many many kinds of love. The love you've fallen in might not be the romantic kind in the end, but if you feel that you love the person you're talking to - then you just do (because love is a/the feeling). See what it grows into....
Also - don't forget that when you're only connecting with one aspect of a person there is a tendency to fill in the blanks a bit. Be happy with the love you've got there, and try not to constrain it by creating an image of perfection that could be difficult to live up to.
