A girl I like who claims to like me as well just posted "Never choose someone who's unsure about you." What can a guy do to show a girl he's sure?

I told her I like her pretty early into meeting her, and she said she liked me too but our beliefs don't align, and she might be moving far away. Not sure yet though. We had this conversation maybe a month ago, and I've seen her 3 times since then, but we've been texting each other. Out of respect for her beliefs, I haven't pushed anything on her, and I said I would cool it with talks of romance so we could get to know each other more, and I've done that for the past 2 weeks.

Do you think she's talking about me? I'm not super convinced she even likes me that much because usually I have to be the one to reach out, but she usually does respond positively. We don't see each other often, but I saw her two days ago for brunch.

Even if she's not talking about me, I'm curious to know what to do in the future.

The truth is that guys often are sure, but girls don't feel that guys are sometimes, and I want to know what's going on in your minds. What makes you feel this way? What is or isn't he doing? Please share stories/experiences.
