He vanished after saying he liked you? What to send next

The first thing to look at is how long the gap is, not the wording of his last message. A week after saying he really liked you is a long time in early dating. Most people who are still interested reply within a day or two, even if it's just a short "sorry, crazy week." A week with nothing usually means he's stepped back somehow, whether or not he meant to.

Look at what happened right before the silence. Did the conversation move toward a date, a more personal topic, or something that made him feel he was being pulled along? Some people get cold feet after saying something warm, because saying it made them feel exposed. Others just had a busy week and let a thread drift. You can't tell which from the outside, so don't spend energy trying to decide. Your job is to give him one clear, low-pressure opening and see what he does with it.

A good reply to this needs to do three things. It should be light enough that answering costs him nothing. It should be specific enough that it's obviously about the two of you and not a generic "hey stranger." And it should make it easy for him to answer with a concrete next step, not just a vague "haha yeah."

Specific usually means referring to something real from your earlier conversation, a detail he gave you, or a plan you talked about. That shows you were paying attention and gives him a thread to pick up. Keep it to one message and one question at most. A question he can answer in a line works better than one that needs a paragraph. Don't mention the silence, and don't bring up how much he said he liked you. Both put him on the spot.

Timing matters more here than people expect. Send your one message during a normal part of the day, so a reply doesn't look like a late-night reach or a rushed reaction to being ignored. A weekday late morning or early evening is usually fine. Skip sending anything after a drink or while you're feeling the sting of the silence, because those messages tend to come out longer and more pointed than you meant.

After you send it, give it real time before deciding anything. Two to three days is a reasonable window for a reply to a light message. If he responds warmly, match his energy and move toward a plan. If he doesn't respond at all, don't send a second message with more emotion in it. One follow-up at most, shorter and even lighter, and only if the first one clearly got buried rather than ignored. If that gets nothing either, stop. Take the silence as his answer and put your attention somewhere that will give it back.
