Mixed signals please don't judge:/?

I'm gonna be open and honest about this, ok so I went on a cruise and on the first night I met my waitress, her name was miglena and she is from Bulgaria. And I instantly feel in love with her. So anyway On the last night of course I didn't want to leave her because I liked her so much, so we went to take a picture and I put my arm Around her shoulder, and she put her arm around my side and she was like rubbing my side, I was shocked, so everytime I went to hug her she was rubbing my back, I'm not sure if that's the way they say bye in Bulgaria, I just don't know. And I'm not a lesbian or anything this is only like the second time this has happend. I just need advice from someone who's has a little bit more experience than me. I know this is a weird question but I'm really having a hard time with leaving her I miss her so much:/
