It's not a dumb question. It's asked a lot and for good reason, it's not always easy to tell when someone likes you. Here are some signs to look for- He looks at you a lot, he smiles at you sometimes, he is (or tries to be) funny around you, he tries to be helpful, He tries to show off or tries to convince you he's smart. If he knows you he might talk to you only a little or he might ramble on a lot. These are just some basic things and a lot of it depends on how aggressive he is. Hope this helped.
Usually a guy will look at you a lot not like gawking or staring just looking a lot, want to be around you a lot more and all, and maybe talk to you about seemingly dumb things but wants to get a sense of what your personality is and if you would in his mind be capable of holding a fun and interesting conversation, other than that he will just want to be near you a lot. :)
Well me and the girl I like are a little shy but not a lot and when we talk I can feel a connection immediately. but besides that if he has a mix of caring about you and a mix of not caring about you then he likes you. I mean when you guys are around it seems like he likes you but then when your not talking it seems like he could care less.then he most likely likes you
If he likes to look at you, tries to touch you often, and smiles at you, for some guys. Others will be really shy, hovering constantly on the outskirts of your group but never really talking to you. Some will be aggressive, messing with your hair, spinning you around and teasing you.
The real thing to look for is that he's treating you differently than he might treat other girls who he knows as well as he knows you, and who he likes as much (as friends) as he likes you.
To know, first you have to talk to him...the main sign is that when your talking to him he looks more to your mouth than your eyes. The second thing and it's found in most guys is that he tries to follow you every where you go and with that I meant in the surrounding place you two are in (like:school) and don't worry he doesn't have to follow you every second...these were the two main signs to know. Good luck and your question is smart...it's repeated but smart...it's not a dumb question!!
