He blows a kiss?

Sounds dorky, but yea its flirting

Duhhhh... You should go in for the real thing the next time he does it.

just putting my 2 cents in. I will blow a kiss to be playful if I know she is also playful, or its an inside joke, like if you blew kisses to him first. It is flirting but I myself flirt with any girl its in my nature, but I only flirt with girls I like so yeah its flirting but it may not be really serious.

Ask yourself, do you see him doing this with other girls?
Also, is this all he does or does he give you more attention then others?

If you want it to be, it is.

I mean generally you don't blow kisses to people you don't feel things for. I wouldn't blow to a kiss to my grandmother, for instance.

Indeed it is flirting.

Absolutely

Guys will not do this unless:

1. he's gay.
2. he likes you.

YES ITS FLIRTING

Oh he's deff. flirting :-)

Flirting... unless he does this to every girl he says bye to, because then that's just his thing...

is this a serious question?
Obviously you already know the answer.
