She said yes to dinner... but!?

So I'm interested in this girl. I texted her to catch up. She asked me how I was and what I had been up too and she said she wanted detail. I said if she wanted detail it would be better in person and she said she agrees. We were going to meet up in the afternoon but I was still busy and she said she was getting tired so we postponed it to the next day. Next day came and when we were going to hang out she said it would be better the next day because she was just off work and was tired. So I asked if she would rather just have dinner with me on Saturday and she said yes. But we don't really text much or she takes a while to text back. But when she texts she always puts happy faces and shows that she enjoys talking to me. I'm just curious if she would be interested in me or just being nice.
