Should you text immediately after getting their number

If someone exchanged numbers with you, they already said yes to hearing from you. That decision is made. What you're texting about now is not whether they want to hear from you at all. It's whether you're someone they want to keep talking to once the momentum from meeting has worn off.

Immediate texting works against you here because it doesn't let that separation happen. You're still in the same conversation thread in their head. Hours later, when you text, you're starting something new. That shift is what makes it interesting instead of just an extension of something already happening.

Don't try to be funny, deep, or clever. Don't ask them how their night is going unless something specific just happened that you both know about. Don't reference inside jokes from the conversation unless you're sure it'll land the same way over text.

A good first text references something you talked about or makes a small observation that gives them an easy reason to reply. It's short. It shows you were actually listening. That's it. The goal is momentum, not impressing them. Save the personality for later when you're actually talking.

If you got their number at 9pm, texting at 1am is too late and looks like drunk texting. Text at 1pm the next day instead. The window is morning until late evening on the same day you met, or the next morning if it was a late night.

Send one text only. Do not send a follow-up if they don't reply within a few hours. If they don't respond by the next morning, leave it. You've done your part. Sending two texts in a row makes it clear you're waiting for them, and that's the one thing you want to avoid. If they're interested, they'll reply. If they're not, more texts won't change that.
