Same, I really did consider him a friend, and I really, really looked up to him. I don't know, I was happy when he told me my art made him smile. My friends have done much worse things to me then lie to me about art, but I guess it does still hurt. The reason I feel bad for him is because he must have low self esteem to try and do this all to get friends. I think that's what he really needs either way, is some good friends to tell him he doesn't need to do those things to have some. Even though he lied, he really does seem like a nice guy.
I'm sorry about what ever happened to you on gaia.
But the thing is, most of his current friends from LG were his friends before he started lying.
