How do I attract a girl I like?

I met a woman last week for the first time. I bought her food and then we went into the city. We walked around and just got to know each other. She called me handsome and said she loved my hair haha. She also fed me crisps by hand 😂 we were waiting at the bus stop and that look She gave me was so cute. Ever since that day she hasn't been texting me as much. My insecurity is that she's loosing interest. Is there anything that I can do to be more Interesting?
