It is probably because she lost interest, wants to take things slow, or because someone told her to so that way that mean person that told her not to flirt so that way to be mean or even to be with you.
He stops flirting with you he stops staring at you and all the other stuff that guys do.
I don't know if he likes you but he was probobly flirting with you:)
This my friend is called: flirting.
he probably liked you and is trying to make you jealous
when a guy flirts with you then stops either means hes playing with you, he wants you to flirt now or he liked you then he found another person who is flirting back .
you ask her out
Well if he keeps flirting just go long with it and if you dont see him as more than friend then tell him or her that you just want to be friends well to know if he's flirting with you he would say something like: "wanna hang out later?" or "do you want to sit with me at lunch?" and he might nod at you if he's staring hes liking
If a boy stops flirting with you, it could mean he is now interested in someone else. It can also mean that he found out who you really like or want to be with. With no connections involved, his friends now flirt with you in front of him because he is no longer interested.
You might have made him nervous and he got scared but he still likes you but doesn't know how to get over his nervousness.
Of course because friends spend lots of time together :D so after awhile if its true it will happen :D (This doesn't mean flirting stops) ;)
it could mean that maybe he has found something that he doesnt like about you, that was just playing you, or that something has happened that has made him want to keep his distance from you
Flirting is indicating you care for him. Physical flirting would be showing you care by bodily contact.
