He ghosted after I asked what made him laugh lately

A question about what makes him laugh is actually a demand for self-awareness. It requires him to think, reflect, and give you something real. Early on, some guys aren't ready for that shift. They like the ease of banter but freeze when you ask them to actually describe themselves. His silence isn't about the question being wrong. It's about him not having the bandwidth or interest to go deeper. Another guy at the same stage would have answered easily because he was already thinking about you that way. The silence is a read on his actual investment level, not a mistake you made by asking.

If you decide to send something, it needs two things. First, it has to reset the tone. Don't reference the unanswered question or pretend it didn't happen. Send something that stands alone and gives him an easy way back in without making him explain himself. Second, it needs to be low-stakes enough that if he ignores it again, you have your answer. You're not trying to convince him to care. You're testing whether he's gone or just paused. The message should feel like you moved on slightly, not like you're waiting by the phone. After this, you stop.

Two days of silence could be busy or distracted. Three days is a pattern. Once you hit that mark and nothing has changed, you can make a choice about whether a single reset message makes sense. If you send something, send it once. Not twice, not a variation. One message that doesn't reference his silence and doesn't ask for anything he failed to give before. Then wait four more days. If there's still nothing, he's given you your answer twice now. At that point, move on completely. Don't check his profile, don't send 'just checking in' messages, and don't text him something weeks later pretending this never happened.
