Usually, if a girl likes you, she will avoid direct eye contact when you are within arms' reach and will try to sneak glances at you when you are not looking. Also, she will point out her own flaws repeatedly to avoid embarrassment.
Find a girl who likes stuff that you like.
Find a nice hobby to refocus your attentions.
Find another girl that you like that DOES like you.
Find out what she likes and then start to hang out with her and she will start to like you ;)
The girl has already chosen your friend. Find a different girl. .
Ask her.
If you like a girl you have to find out if she likes you. To do that you hang with her and you spend time with her too.
Then you go out there and find someone who deserves you.
If you really like her you should try to find out what she likes and try to make yourself more like that.
I am in a similar situation: I like a girl who also likes me back, but now I am starting to like her best friend...idk what to do but I think whichever one you find easier to talk to is the one you should go for
then it possible that he likes you, or just trying to find someone, but more likely he likes you.
Find out if she likes you too, preferably by asking her.
