Is this guy interested in me?

i agree with the other guys and try to him get to be alone with you like study or sumthing, sublty find out if he has a girlfriend. some closetted boys tend to other compensate by braging about his many ual conquest with girls. also if you can invite some other people over as well, why you ask well if you can get people to play spine the bottle or truth or dare to give you an excuse for kissing him. you'll know if he is into you if he does it for a long time or slips you the toungue lol but be carefull though if you tell him outright he might not talk to you again, be uncomfortable around you, proberly even ignoring you. step lightly okay and about the eye contact if he does it alot it might be that he is into you or just being polite also the talking to you just might be him being friendly. but if your willing to gamble i suggest getting him alone and telling him how you feel. just be ready when he replies because it might end up being harsh good luck
