Did I do something wrong...?

[Xhilo]

Actually your message to him was that of innocence and does not hint at any affection towards him. You simply told him he did a good job and congratulations. The fact that he did not answer does not necessarily mean that you like him. Sometimes I myself do not reply to a facebook message because I don't notice the notification icon....or maybe he is one of those people who has facebook and doesn't use it?? Nothing wrong was done. Don't be afraid to walk by him. And If you messaged me saying that...I wouldn't automatically think that you liked me
Good luck
