He texts during the day but ghosted after you asked him out

There's a difference between someone who enjoys talking to you and someone who wants to see you. Daytime texting is low stakes. It's entertainment, a mood boost, a way to feel connected without any real commitment. It can happen while he's also texting other people, while he's busy, while he's thinking about other options. The ghosting after your ask tells you which one he is. He liked the texting dynamic enough to keep it going, but the idea of actually meeting up, of taking the interaction into the real world where he has to be present and make a choice, made him pull back. That's not a mixed signal. That's a clear one.

Your reply needs to do two things. First, name what happened in a straightforward way that doesn't accuse but doesn't excuse. Don't soften it or make jokes. Just acknowledge that he went silent after you asked him out. Second, give him a binary choice without spelling it out. Either he's interested and he says so with a specific plan, or the conversation stops. No middle ground where you keep texting and he keeps ghosting. The tone is calm and direct, not angry. You're not invested in his answer. You've already moved on in your head, and your message should reflect that.

Send your reply within a day or two of noticing the silence. Don't overthink the timing. Just send it in daylight, when you're clear-headed, not at night when you might soften the message. Then don't send anything else. If he responds with a real plan within a few days, you can decide whether to trust it. If he responds with excuses or keeps texting like the ask never happened, you already have your answer. If he doesn't respond at all, that's also an answer. Most importantly, move your attention and energy to other people. Don't check back in after a week hoping he's changed his mind. Once you've made the pattern clear and he hasn't stepped up, there's nothing left to do.
