What to do if he introduces himself as single to other people

Start with who heard it. If he said it to a friend of yours, or to someone at a bar you were not at, he may be using single as shorthand for not officially together without thinking how it lands for you. If he said it while you stood there, or to someone who went quiet once they learned you were seeing him, that is harder to read. You need to know whether he sees you as part of his picture and called himself single anyway.

Then look at how far things have gone. Three weeks of casual dates with no talk of exclusivity leaves a label unclear. Months of weekends and a drawer at his place does not. The gap between his words and your actual routine tells you more than the word single.

Name the thing you heard in plain words, then ask what he has been telling people about where things stand between you. Keep the question on his label and on what he thinks the two of you are, because that is the part you can actually use. Do not ask him to prove he is not seeing anyone else. That invites a yes or no he can dodge without saying anything real.

Leave out the details that make him defensive. You do not need the friend's name, the bar, or the exact wording if the core claim is clear. Those details turn the conversation into a hunt for who talked. Skip any line about how you would never say that about him, since it puts you in the position of being judged. One direct question with the claim attached gives him a clean opening to answer honestly.

Give him until the next day before you read anything into the gap. Someone who wants to answer properly often needs a few hours to think about what they said and to whom. If he replies that night with a clear answer, you have your information. If he replies with a joke or changes the subject, that is still an answer, and you can ask once more, directly.

If the silence runs past a full day, do not send a follow-up that repeats the accusation. One short message asking for his answer is enough. If the next day passes too, stop waiting for a conversation and decide what you want to do about seeing him. A reply that dodges twice, or that tells you the question was dramatic, has already answered it.
