How can I know if she is interested in me through text and in person?

I'll try to make this short. I met this girl on a dating app and we've been talking everyday, good morning, throughout the day, good night, and we even say to text each other if one of us wakes up or can't sleep. We met in person for the first time yesterday and we had lunch together then to Target to browse around. She said the only reason she wouldn't date me is because of my height (I'm too short), she said that she would ahve to see how we vibe in person and warm up to it. When we were in person she did the iPhone add thing where you touch phones to add contacts. And she also told me she deleted the dating app although she said that I didn't have to delete it and she was going to delete it anyways.

Throughout the day she'll send me selfies (which I'll heart and compliment her), she'll send me TikToks, she'll say things like "hehe" and use extra letters (she started doing this after we met) like "okayy" and "wymmmm". So I'm having a hard time knowing if she IS interested in me, but just has to warm up to my height before we start dating or what? What are some signs to look out for? Thank you!
