Should you text her all day or only when there's a reason?

Frequency only means something once you know what the exchange looks like. If she's sending long replies with questions back to you, she's invested and daily texting will feel natural to her. If her replies are one or two words and she rarely asks you anything, the thread is thin, and more messages won't fix that. Look at whether she starts conversations sometimes or only answers yours. A person who initiates now and then is giving you a signal you can build on. A person who only answers is telling you the current pace suits her, even if she never says so.

Also check what you two already have. An inside reference, a plan you discussed, or a detail she offered about her week gives you something to return to without starting from scratch. That is much better material than a general check-in, and it's what keeps daily texting from feeling like upkeep.

Once you've decided to text in the middle of the day, the test for each message is simple: does it give her a specific thing to respond to? A follow-up on the vet clinic story, a question about how the dog did after surgery, or a link to something you think she'd find funny does that. A message that only says you were thinking of her does not. Keep the messages short and open. One clear point and one question is usually enough.

The other job is to keep the line of the conversation pointed somewhere. If you started with the dog, the next message can be about the weekend, or a restaurant you both mentioned. You're building a path toward meeting in person, so each text should either add a small piece of shared context or move closer to a plan. Small steps like that make the daily contact feel purposeful rather than like filler.

You don't need to reply to every message quickly or fill every silence. If she goes a few hours without answering, that is normal, and sending a second message right away usually makes things worse. Give it a reasonable window, often the rest of the afternoon or the next morning, before you consider following up. A single follow-up that references what you said earlier and asks something new is fine. Two follow-ups with no reply is the point to stop and wait for her to come back.

If the thread goes quiet for several days with no response to your attempts, step back. Keep the last message simple and don't chase with apologies or guesses about why she stopped replying. Then move on. Most of the time a gap like that means the interest wasn't mutual, and it's better to find out early than to keep sending messages that feel one-sided.
