What should I do if a girl stops responding to my texts?

Before you send anything, reread the last exchange and look at how it ended. If she closed the conversation herself with a goodnight, a work reference, or a plan she had to get up for, the silence is probably ordinary. People drop threads all the time when their day moves on. If the conversation was going well and then stopped mid-thought, or if her replies were getting shorter over several days, that's a different signal. It tells you whether a light follow-up will land or whether you're about to chase something that's already faded.

Also check what she actually asked you. An unanswered question is more likely to get a reply than an unanswered statement, and a question you left hanging might be the reason she hasn't written back. If she asked something and you never answered, that's your opening, not a sign she's pulling away.

A follow-up that works continues the actual conversation. Refer to something specific she said earlier, like the sister she mentioned or the early start she had, and add a small new piece to it. Keep it short enough that replying takes no effort and open enough that she can answer in one word and still be fine. You want a message she can glance at while doing something else and still feel like answering.

Leave out anything that announces the silence, any apology for texting, and any question about her interest. A message that says sorry for bothering you, or wonders if you did something wrong, makes the whole exchange about the gap. Keep the text about the topic. If it reads like something you'd send a friend you were catching up with, you're in the right range.

Give the first silence a full day, and closer to two if the conversation was active. A text sent at 2am or in the middle of a busy afternoon often gets buried, so send your follow-up when people actually check their phones, usually late morning or early evening. Sending it at roughly the same hour you sent your first message tends to work well, because it fits the rhythm she already has with you.

If there's still nothing after one follow-up, don't send a second one for at least several days. If she doesn't respond to that either, let it go. Two unanswered texts a few days apart is a clear enough answer. Send nothing else after that unless she reaches out first, and if she does, reply normally without bringing up the gap.
