I need some help. How do you know if a guy is flirting with you?
You need to be 16 to get a serious answer...
you're 13. don't worry about boys yet. they are all still too immature for relationships. the reason they act the way they do is because they're starting puberty and their hormones make them "stupid", for lack of a better word.
He will be smiling more, hanging around, doing things he didnt really do before now hope this helped:)
