SHOULD I PURSUE THIS GIRL I MET ON A CRUISE? don't want to come off too strongly ! ADVICE PLEASEEEE?

I think she's just teasing you, I think you should call her and ask her for a dinner or something, worse comes to worse she's gone say no. then at least you know if she was interested or not, but don't give up hope because 90% of the times when girls say no they mean YES, so even if she said no, try one more time like a week after.
