For me chatting with a girl is like a chess match. I try to think ahead. I always keep a ratio in terms of length of my messages or make some statements so she can ask me something.

So tonight I texted one girl to meet tomorrow. She said yes let's go. I send her location and time.

She didn't confirm but saw my message.
Hopefully she gonna reply with some confirmation tomorrow but If not I wouldn't be happy to send her two messages in a row. Seems kinda needy.

Any advice ? Maybe I am overthinking it
