How do you tell a guy you're not interested in him?
How you say it doesn't change: be direct but respectful of his
feelings. What you say depends upon the situation. Have you been
seeing him long, or have you dated only a few times and have
decided you no longer wish to pursue a relationship with him? Or
has he asked you out but you've declined by making excuses? Or is
he simply flirting and chatting with you and hasn't even asked you
out yet, and you hope he doesn't? All those situations are
different and will require different ways of handling them.
Clearly, the less time you've been with him, the less time you'll
need to spend explaining your feelings. If he's asked you out and
you've made excuses, he may not have inferred that you aren't
interested. So the next time he asks you out, you must not give
false reasons for declining. You must tell him frankly but politely
that you don't wish to go out with him. If he hasn't asked yet but
tries to chat it up with you, tell him you're very busy and don't
have time to chit-chat. You can't preempt his asking you out, but
if he ever does, decline frankly and politely. No false excuses for
why you can't. In the cases where you've been dating, you'll have
to determine the time and place for it. If it hasn't been long,
just wait for the next time he calls you and let him know then. It
needn't be done in person. If you've been seeing each other for a
time, well, then it's more respectful if it's done in person.
