Just be yourself.Let things flow.Thats what I do.People say that i flirt a lot but i don’t even know.I’m just being myself.But if you actually want to try to flirt back, you could look at him a lot and when he looks at you turn around quickly then slowly turn your head and look back at him and relax your eyes and keep eye contact a little longer than usual.Thats the key sign that somebody is interested/likes you.
Oh and for him to admit he likes you, tell him things you wouldn’t tell your friends and talk about your problems with him.Or if you are bold enough just straight up tell him, “I have something to tell you, and it’s really important…[3second pause to take a breath] I like you.”Most likely if it’s just the two of you or nobody is close enough to hear you, he will tell you whether he likes you or not.

i’m sure you flirt back without even knowing it. if he likes you, then why more flirting tips? and when it comes to getting him to admit he likes you.. all you have to do is talk about how cute/hot/sexy he is and your in. if you aren’t comfortable with that just ask him strait out.

use the Straight approach hes scared that all or he might be the kinda guy who’s scared of commitment

Invite him to movie or dinner then you can talk to him baby

dont flirt, thats gross
