You can only tell for sure that a guy likes you if he says so.
to tell if a guy likes you just be yourself around him and if he really likes you and he can tell your comfortable around him then you will know
The same way you tell if a girl likes you.
if he likes you for who you are
if he hits on you
If you are in 4th grade, to tell if a guy likes you is:If he is always bugging you.If he always talks to you.If he smiles at you.
if a guy likes ur friend he will flirt with her and not u.
If a guy likes you he will turn around and look in your eyes.
if a guy likes you but you dont like him, tell him your not in to him and say sorry.
If he flirts.
I will tell him to stop,or i will like him back
You can tell if a guy likes you or if you like him a lot if you often spend time with each other.
You should tell the guy who likes you that you don't like him, but not until you ask the guy who you like if he likes you.
well tell him how you feel and if you like him then tell him that your friend likes him and all of you get together and discuss how to solve the problem and if she gets mad with you then tell that guy that likes you to talk to your friend and explain to her how he feels about you so she can know that she has to move on or if not tell HER what's going on with him and you Good Luck .....
The way you could tell if a guy likes you is by the way he reacts around you and especially if he runs away from you now that's how you find out if he likes you.
Tell him your straight.
If he likes you, you will know.
You have to ask him.
Trust me. You will know.
