What actually shows that a guy likes a girl?

Ok if a guy is either trying to get you to notice him or he is noticing you. If a guy starts asking you questions out of the blue he probobly likes you. He wants to strike up a conversation. Also if you catch him looking and looking away when you look at him. A lot of times guys are also pre rehearsing there speach they are gona give you so that's why they are glancing at you a lot before they approach you. They may be thinking about how to approach you for a half hour or even longer. Some guys take weeks. So if you catch a guy glancing at you or asking any question its a sign he likes you even if he asks you about the music or place you are at. Also if he is doing stuff around you like talking load to his friend he may be trying to get your attention. If he does not look your way makes no attempt to show off and is totaly concentrating on something else then he doesn't like you or hasn't noticed but be carefull sometimes we look when we think you arnt looking. So any attempt to get your attention or any attempt to get a conversation going or any look at you more then once. It means he is probobly interested now go make a move and real him in. He willl like it if you make a move

Lots of smiling an him being interested in the majority of what you have to say, also the way he looks at you, not a "o gawd he's undressing me with his eyes" kind of looking at you I think you'll know what I mean when you get that look I'm talking about, I hope this answer helps.

Hand on the chin head leaning forward stairing into your eyes as if he had never seen eyes so beutiful before.

ok, I struggled with this question for over a year, then finally the guy gave in and asked me if I would go out with him. (now we've been together for almost four months) and some key behaviour that tipped me off that he liked me from the start:

--He constantly wants your attention. He'll do anything to make you look at him, laugh at him, or talk to him.

--He sometimes stares you from sidelong glances, or he'll just try to catch your eye.

--He'll make any stupid excuse to talk to you, and ask you stupid little questions that don't really matter.

--He'll ask you what you think about certain things. This is very important. It means he values your opinion and wants to know what your thinking.

I hope I helped at least a little? Good luck in the world of dating!
