Mirroring his energy too literally

If he sends one word, you don't have to send one word. If he goes short, you don't have to go short. The logic of strict mirroring — matching his exact energy to avoid coming across as too eager — misses something important: you have your own register, and your own register is attractive precisely because it's yours. Mirroring can be useful in the early weeks when you're still calibrating, but taken too far it turns into a reaction game where neither person is really showing up. Bring your own warmth without overcompensating. If he's had a flat day and sends a short reply, it doesn't mean you need to match his flatness — it means the conversation is low-energy right now, and you can either gently lift it or let it rest. The goal is not to perfectly reflect his current state but to maintain your own presence within the dynamic. The version of you he was drawn to had its own distinct energy. Protect that.
