Why would a guy compliment my jacket? Is he interested in me? yes/no

Basically there's a guy I knew from a class in university last year. We didn't talk much but he added me to fb, complimented my work in class and stared at me a lot.

Anyway, THIS WEEKEND my family and I attended a comic convention. My family's business entails attending venues as "exhibitors" and selling related merch. It was a four-day event and it turned out"Nick" happened to be at the convention too. He went to my booth and he hugged and we spoke a bit. He bought a snack from me too.

He came back on the third day, when I was dealing with a customer and was just watching me for a while, then we spoke a bit more, but I was busy so he said he'd "leave me alone now." He came back on the last day of the convention, with a few friends, and asked how the convention sales were, and showed me what he bought.

He complimented my jacket randomly too. The whole time we made a lot of eye contact but I always looked away first. Anyway, as they were leaving he waved and smiled, wishing me a good summer. etc

So was this all friendly stuff or flirty? Just wondering. I can't tell if these interactions are normal between opposite gender friends (acquaintances?) or if he is showing signs of interest. He had a girlfriend earlier this year, but I believe they've since broken it off. Anyway I'm confused. Opinions or/and advice please. Thanks!
