What does she think of me?

I'm 15 and my friend likes this girl so I went with him an hung out with her and her friends. We all just hung out and talked and I'm not sure if one of her friends like me. She met my mom and she said she loved her and stuff. Then my friend was texting the girl he likes and somehow it got brought up that I'm really ticklish and she said like her friend gave her a devilish eye and said oh really like she was going to tickle me the next time we seen eachother. And she made up a joke that we are married. The next day we hung out and she was like we are married and stuff just joking around. I didn't really do anything flirty we all just talked but one of her girlfriends was about to give her a piggy back ride and I said I would and then I gave her one instead and when she was on my back she said I smelt good. I haven really texted her or anything or asked for he number. I'm not sure if she thinks of me as a friend or more an im not sure if I like her as a friend or more. What do you think?
