Is it too much to text him a second time in one day

A few hours of no response doesn't tell you much. He could be at work, in a meeting, or just not checking his phone. The problem starts when you assume his silence is a signal about your interest level and try to fix it with another message.

If he's interested, a second text won't make him more interested. If he's not, a second text won't change his mind. What matters is whether your second message gives him something real to respond to. A random check-in or 'thinking of you' text is asking him to invest energy in a conversation that might already be fading. A text with a specific question, a plan, or a real reaction to something he said gives him a reason to write back.

Reference something specific from your first message and add new information. Ask a concrete question that's different from what you already asked. Share something that connects to what he said earlier, not just send more of your own thoughts into the air.

If he sent a photo or told you about his day, your second message can build on that. If your first message was a question and he ignored it, your second message should not be another question. Instead, move forward. Make a plan, change the subject, or make a statement that doesn't require him to do the work of figuring out what to say.

Stick to one message per exchange. If he doesn't reply to your second text within a few hours or by the next day, stop. Sending a third message the same day or the next morning reads as pressure. He has your message. He knows you're interested. Another one won't help.

If a full day passes with no response, you have your answer. Move on to someone else. If he comes back later that week or next week, great. But don't fill the silence by texting more. One text every day of silence becomes pestering fast.
