Is it normal to double-text?
Mostly.Normal for most people
Yes, double-texting is normal. A follow-up message is usually no big deal; sending a string of messages when someone hasn’t replied can feel like pressure.
People double-text for all kinds of ordinary reasons: they forgot to add something, had a new thought, or just don’t treat texting like a strict turn-taking game. One extra message usually isn’t a big deal, and plenty of people won’t think twice about it.
The vibe depends more on the context than the number of texts. A casual follow-up is fine; repeatedly messaging someone who hasn’t responded may come across as pushy, especially if they’ve asked for space. If you’re unsure, send what you mean, then give them room to reply.
