How do you get a boy to like you?

I have a crush on this boy i’m talking to and there are constantly girls prettier around him and i feel horrible about it. i wonder if i’m even worth his time. my friend said he’s possibly flirting with me but i dont know. i’m not the girl men flirt with, or like generally. i dont even have any guy friends because i’m like, dude repellent. its hard.
