she wants to see if you are worth the smooch
Usually he keeps looking at you OR he might come and join the conversation. Sometimes they even send a friend to join in the conversation with them
Its mabye because he still feels attracted to her, its normal with puberty and such with horomones.
i wont disturb him
a way to know if he likes another girl is if he keeps looking at her and smiling also if he talks about her with his friends.
She likes you, but doesn't want to mess up the relationship she is in right now. If they were to break up, you would have a very good chance to go out with her.
when he keeps looking at you and winds you up! Probably he will treat you different to any other girl and he will be extra nice to you. BUT ANOYING
If a shy guy keeps looking at you, it could mean that he is interested in you but is too nervous to approach you directly. He may admire you from afar and be too timid to make the first move. It could be a sign that he wants to get to know you better but is unsure how to initiate a conversation.
Because he likes you and is jelious of your boyfriend
A safe haven
I was just kidding this never happens! But if this does happen to you and you don't like it end the relationship or just have a serious conversation with him about it
Ask him
Pray and move on...
