YES! These are the signs of liking back.
If a boys flirts with the girl after knowing that a girl like him the boy definitely likes her otherwise if he didn't, he would rather avoid the girl.
To be more sure you certainly have to ask him.
That's the solution to the problem.
If you like a boy then you should ask him if he is having a happy day when he is not having a happy day. That is how I got my 5 boyfriends. Ask him if he has a cell phone if he says yes then write your home phone or cell phone number but don't give it to him, just put it on his desk or in his desk.
Flirt back he will eventually come to it and see that he likes you to
He has an interest in you and hopes you like him back.
If he starts conversations with you. If he flirts/flirts back at you. Also is if he will come up with random things to talk to you about or find any excuse to talk to you.
Flirt a lot and spend alone time with him and see if he flirts back
tell her to stop flirting. besides if she does that you shouldn't be her friend
depends if you like him then flirt a little don't write him a note . if he flirts back he likes you . then ask him out.
Go along with it.
Depending on how he flirts, do something that corresponds with his actions. So if he is talking with you, don't turn your back on him or make it short, take your time.
tell him do you like me or not? make up your mind! even if you like him, don't worry, he needs to make up his mind if he likes you or not.
Well,it means exactly that he's a flirter and is not really an honest guy.
try to do things to make him like u back
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 .
