How to stop overthinking what a text really meant

A reply like "haha nice" to a long message usually means she read it, liked it, and had nothing extra to add in the moment. People text this way at work, on a bus, or while half-watching something. The brevity is about her bandwidth, not a verdict on you. Check whether it fits how she normally texts. If she usually sends paragraphs and suddenly sends three words, that's a more useful signal than the three words themselves.

The mistake is treating the message like a test you've passed or failed. One text tells you very little. Her pattern over several days tells you a lot more, so wait to see that pattern before you draw any conclusion.

A good reply here is short and easy to respond to. Acknowledge what she said without asking for more, then give her one small thing she can pick up if she wants to. Pick a detail from her side of the conversation, or ask a light question she can answer in a few words. The point is to give the exchange somewhere to go without making her feel she owes you a long answer.

Avoid replies that ask her to explain herself, reassure you, or justify the length of her last message. Those turn a low-key exchange into an interrogation. Keep your reply about the same size as hers, or one step bigger, and let her decide how far to take it.

If she doesn't come back after a short, friendly reply, leave it alone for a full day before doing anything else. Replying an hour later often reads as anxious, and sending a second message that evening usually turns a quiet moment into a pressure point. A day of silence early on is normal and rarely means much by itself.

If you've sent one good reply and heard nothing for three or four days, it's fine to send one more light message with a new reason to talk, like a link or a question about something she mentioned. If that also gets nothing, stop. Two unanswered messages after a clear sign of interest is an answer, and chasing it only makes the conversation harder to recover.
