Is it flirting if all you do is tease each other?

I see my guy friend (this has been going on 5+ years) 5 out of 7 days of the week. He tends to be hot and cold as the day goes on (but then again so do I). I don’t think it can be anymore than flirting because I’m leaving in a few months and he has another year of high school left.
