How do I know if he's a player?

I just met this guy and he seems really nice, into me, and txt me alot whn he has time but...I'm wondering if he's a player. He goes to clubs alot and I see pics of him dancing with females and drinking. We're not going out or dating yet because I havent decided. I'm being cautious because I dont want to get played and he's a pretty attractive guy. Is he possibly a player?
