What are some examples of dry texting?

A single short answer tells you very little. People answer questions at work, on the bus, between errands, and their replies often shrink when they're tired or distracted. Look back over the last few days of the thread. If she was giving longer answers early on and has trailed off, that's a real change. If she's been terse from the first message, she may just be a terse texter, and better wording won't fix that.

Also check whether she ever starts anything. Someone who's interested usually brings something up, even if it's small: a photo, a question, a link, a joke about something you said. If every message is a reply and nothing comes from her side, the thread is probably low priority for her right now. Good to know before you put effort in.

Yes or no questions, and open questions with an obvious answer, invite the short reply you already got. Questions that ask for a choice, an opinion, or a small story work better. Ask her which of two plans she'd pick, what she'd order at a place you both know, or what she thought of something specific. That gives her a natural reason to write a sentence.

Keep the question light and concrete. A question that asks her to reveal something heavy tends to get backed away from, especially early on. You want replying to feel easy, not to dig for depth over text.

Texting is a poor tool for building interest when one side is holding back. The fastest way to learn whether there's real interest is to move things to a call or an in-person plan. Suggest a specific time and place, like a drink on Thursday or a walk Saturday morning, instead of asking whether she's free sometime. Vague plans get vague answers.

If she agrees and then the plan falls through, or she keeps deferring without offering an alternative, that tells you something. If she engages with the plan, asks where to meet, or suggests a time, the dry texting was probably just texting.
