Pay attention to his actions and body language. If he is particuarly nice or nervous around you he probably likes you but not definitely. If things are pretty much normal play it safe for now.
Vist this wikihow page: m.wikihow.com/Know-if-a-Guy-Likes-You That should help, it did for me
you can get a guy to tell you if he likes you by just being yourself or just coming out and asking him, "hey do you like me?" what do you have to loose?
Thats hard, but who cares.Give him a note, tell a friend to, etc. Anything that lets him know what your asking.
He doesn't like you
well sometimes he sits by you on purpose and he tries to tell you funny stories or sometimes he just wants to be your friend.
if he trusts you, tell him what you think about the girl he likes. if he doesnt stop liking her then, try asking him WHY he likes her. it might get him thinking...
if she looks at u all the time or is shy around u or likes to make fun of u.
Go up to him and say hi. If he says hi without laughing or anything, he probably likes you. If he picks on you, he probably likes you. Ask around to see if he likes you.
what i do is build trust or keep asking 4 me it works but only sometimes
If your that desprate try asking him and if he says no then just move on
tell her while shes drunk
If he stares at you, smiles and is really nice to you then he probably likes you.
