Does he want another date if he never suggests one?

No suggested second date is one data point, and it's the weakest one. What matters more is what his messages do after the date. If he replies quickly, asks follow-up questions, brings up details you shared in person, and makes small jokes that refer back to the evening, he's engaged even without proposing a plan. If his replies are short, delayed by a day or more, and never ask you anything back, the story changes. Look for effort. Someone who wants to see you again usually puts some energy into keeping the thread alive, even if he's too shy to ask for a date outright.

Pay attention to whether the conversation has any momentum. Two or three exchanges that naturally lead into a topic you both care about are a good sign. A single "haha" followed by silence is a weaker one. You can also watch for whether he ever tries to steer the chat somewhere, like sharing a link, asking about your weekend, or mentioning a place you'd both like. None of this is a guarantee, but it gives you a far better read than an empty calendar.

A good follow-up does two things. It shows you enjoyed the date, and it creates a small opening he can step into without effort. The first part can be specific. Reference something real from the evening, a story he told or a detail you noticed, so he knows you were paying attention and not just being polite. The second part is trickier. You want to leave room for him to suggest something without asking him directly for a commitment. Mention an upcoming event, a place you've been meaning to try, or a topic you'd like to pick up again. That gives him a natural hook.

What you want to avoid is doing all the planning yourself in the first message. Proposing a specific date and time before he's shown much initiative can read as eager, and it puts him in the position of agreeing or declining on the spot. Let him take the next step if he wants to. If he doesn't pick up the opening after one or two tries, that tells you something too, and you don't have to keep building the bridge alone.

Most people reply to a post-date message within a day, but some take longer, especially if they're busy or unsure. A gap of two or three days is normal and doesn't mean much on its own. If you've sent a warm message and he hasn't responded in four or five days, you can send one light follow-up that doesn't ask for anything. A funny link or a quick update on your week works well. It gives him another easy way to reply without making the silence the focus.

If that also goes unanswered, or he replies with something flat and moves on, it's reasonable to stop. You don't need a confrontation or a clear answer about whether he's interested. Put your attention on people who put effort into keeping in touch. Checking his profile or rereading old messages keeps you stuck, and the pattern will usually be clear by the end of the second week of quiet.
