The whole 'already found someone else' thing doesn't surprise me to be very honest. But I don't believe it's a real life relationship either.
If someone I was dating online would tell me "you don't deserve seeing me on webcam/hearing me on microphone" I would've told that person "screw you then" and leave. Three years of not knowing who exactly you've been intimate with, sharing your life and secrets with, is creepy to me.
Even if that person didn't want to show herself through cam/mic, there's a ton of pictures of her, right? It's not hard to prove you're really who you say you are by just taking a picture of your face and a piece of paper with your (or her) name on it. But that's just me.
Don't forget; A fault confessed is half redressed.
