So what if she refuses him? He is bad enough now, he didn't tell her how he feels, and he has to listen to both of them (her and his friend) telling him how they chat to each other and how are they having good time. That's worse than being refused after he told her about his feelings.
As Rab said, he may tell her that he likes her (if he thinks that she may respond even a little bit), but not to tell her that he is in love with her.
Indeed, I'm not against your opinion, but I'm asking for more patience.
