How should I interpret his behavior?

I'm an American and I really like this guy from Saudi. We're both in college. I don't know for sure that he's Muslim, but I have little evidence to the contrary. He's a genuinely nice guy and I would really like to date him--we have a lot in common and he has an amazing ability to make me feel better about life every time I talk with him or see him. But from what I understand, Muslims can't date or even spend time alone with a member of the opposite sex before marriage (we have spent time alone together, studying). How should I approach this situation? One time he mentioned getting laid at a club, and asked me to go to Florida with him this past summer break (I couldn't-we're going to Mexico over winter break) but he abstains from alcohol and is generally a huggy person. I don't want to just ASK if he's a Muslim, but I don't know how to bring it up in conversation. Advice? Is it a lost cause? Would my being American matter that much? Thanks! :)
