How often should you text in the talking stage?

We’ve been talking for 2 weeks now. I feel like he doesn’t like me that much anymore. Unless that’s just how he texts. He did ask to meet like two days ago, but our schedule is so crazy. It’s kinda hard to meet for now. I told him that, but he kind of never answered that message and changed the subject. He makes me so confused. We haven’t talked at all today. The other day, I did message first, and he never responded. So I chose to just wait and give it time. At this point, I’ll just move on🤷‍♀️.
