I know I have found the one when...
1. Even seeing a message from them makes me smile. And knowing that she enjoys seeing messages from me.
2. I find myself attracted to her, and can see myself going out on the town with her by my side.
3. A simple word or string of words uttered by either of us can cause arousal.
4. We can't wait to communicate, or meet.
5. She specifically expresses interest in what I am doing, and wants pictures, and adores the pictures.
6. I find what she does intriguing and interesting.
