Does he like me? Or is he a creep?

You didn't think he was creepy until after your friends pointed that out. Friends don't always know what's best for you. Maybe you're just a wonderful person to be around, to talk to... maybe he thinks you are very beautiful. Seems to me this guy wants to get to know you more. At least he was saying he would visit you at the bar you work--- instead of inviting you to his home/hotel or something (then that would be creepy) Doesn't seem like he's coming on too strong, but that's just my opinion. Only thing that matters is how he makes you feel. If he seems creepy to you, then don't see him anymore. Good luck!
