Let's roll it this way...
You find someone that looks exactly like you want. He has the background. You're hooked. You message him daily and tell him home much you like him. You really start to like him. You begin fantasizing a future together. He, months later, says, "I'm really looking for someone from Ohio. You just don't look attractive to me. I'm sorry. Bye."
Now how do you feel? Are you leading this guy on?
