I realized I am a very bad texter. I am kinda withdrawn either way, but I can make conversation in person.

I met this one girl on some happening, we didn't talk, just said hi to each other (business setting). She is a few years older.

She said hi because I was looking at her a lot😂. I found out her name and ig, so I texted her. She responds in 3 minutes. And I was like oh shit what do I do now. We text for like 10 minutes (10 messages). I send some gif I thought was funny - no reply. Then after the fact, I get ideas like. Oh I shouldn't have said this or that. How can I generally improve? Should I send her a message again sometime?
