Should you text him again if he never replied?

Before you decide anything, look back at your first message the way he would have seen it on a crowded phone. Did it ask something he could answer in a few words, or did it demand a longer reply he'd have to set aside time for? A question tied to something specific in his profile usually lands better than a general opener. A message that arrived late at night or early in the morning can easily get buried. If your first text was solid and the silence is only a few days old, there's a decent chance he just hasn't gotten to it. If your first text was vague, or you're looking at a week or more of nothing, the silence is probably telling you the conversation didn't spark for him. The honest move then is to let it go.

Also check his activity. If he's been active on the app since you messaged, he has seen it and chosen not to answer, which is a clearer signal than a dormant profile. A dormant account might mean he's off the app entirely, in which case your message may never have been read.

A follow-up has two jobs. It has to be light enough that replying takes him no effort, and it has to give him a reason to answer that isn't guilt. The easiest way to do this is to ask about something he can answer with one detail: a place, a show, a recommendation. Something that starts a small exchange instead of asking him to explain himself. Avoid anything that refers back to the silence, anything that sounds like a reminder, and anything that asks him to confirm whether he's interested. A second message should read like you're continuing a thought, not waiting for a reply you're owed.

Keep it shorter than the first message. A brief, specific question with nothing else attached gives him a clear, low-stakes way back in, and it keeps you from putting in more than the exchange deserves.

Give the first silence at least two or three days before you follow up. If you do send a second text, send it on a different day or at a different time of day so it doesn't look like a copy of the first. Once you've sent it, stop for a while. If another week passes with no reply, the matter is effectively closed. Keep the app open if you like, but don't start new threads with him, don't like his photos, and don't send a third message in some other format.

If he does reply, even weeks later, match his energy and see where it goes. If he doesn't, the most useful thing you can do is move on to the next match and not treat one unanswered text as a question still waiting for an answer.
