Because he likes the other girl too. If he told you that he likes you, that doesn't mean that he shouldn't or can't go out with other girls. You can go out with other boys, and you should. The time to become exclusive and not go out with others is when you are engaged to be married. Until then, you are free and so is he. Enjoy it and stop worrying about these temporary relationships.
When a guy tells a girl that, he more than likes her, he means that he loves her and is ready for a relationship with that girl.
The girl would probably thank the other guy for telling them the info. Also, the girl would probably ask you to tell the guy that likes her that she likes him/doesn't like him. Plus, by the other guy telling her about the guy who likes her, the girl will be able to either avoid him (if she doesn't like him) or flirt with him. For those of you that don't understand the question, this is the situation: Guy #1 tells the girl that Guy #2 likes her. Guy #1 wants to know what the girl thinks of him. Understand?
if a guy tells you that another girl is beautiful and you are his girlfriend check to see if he is always staring at the girl. if he is not then he only likes the way she looks but he is still into you.
She likes you and hopes your jealous, or she feels close enough to you to tell you that.
It depends whether or not the guy likes the girl. Assuming he does, he wants the girl to...... well, he doesn't really care what she does, he's just happy the girl likes him.
Find a nice hobby to refocus your attentions.
She likes that guy, and thinks that you are a good enough friend that you will help her.
It means that he likes to kiss girls
It means she only likes another guy's face!
Go for the guy
Find another girl or risk getting hurt
There is a few ways to tell if a guy likes a girl. You can tell if the guy smiles at you a lot, talks to you or about you, touches you or tells you.
