Flirting

Is this flirting?

I told this guy I got a job working at a museum but that I wasn't sure about it because it's a classy and elegant place. And he told me I was classy and elegant. Today when I saw him I noticed that he had cut his hair and I told him his hair looked great.

He and I actually slept together once a couple of years ago.
