Why I shouldn't have sent the email? When we talked the night before, I asked for her photo, she replied "but I don't have a photo of you", so I suggested lets exchange them! I did that before with other girls too - always nice to have a photo of someone you liked.
No reply yet. Why do you hope she doesn't reply? I'd think that is a bit disrespectful of her, no? She did say "I want to know how you are doing, dont dissappear off the face of the earth" more than once (this time and the previous time we met).
If I don't contact her for a long time, say a month at least, she might resurface anyway. Life is a cycle. Who knows, we actually might hang out as friends in the future, or whatever. She'd be a useful contact if/when I go to her country for a holiday. About moving on - sure, I already set provisional dates with a couple of girls next week, but her memory will still linger...
