Just simply let them down easy.
They are not awake.
Just say, "thanks, but I'm not interested".
yes
Just tell them, in a gentle but clear way, that you are not interested.
if they are awake. If they are sleeping, it is most likely they are dreaming
You advance the level of involvement, gradually, don't rush things, but if this person stays with you, they are interested. If they drop out, they weren't that interested.
It is hard to tell. Just tell that special someone about your feelings and they will let you know.
It depends on which "sleeping gas" you're interested in.
you can tell they are playing hard to get when the act like they are not interested but still call or text you
Tell her! ignoring her would make her want you more.. or get someone else to tell her
I would say so. He interested in you.
Nothing. You're better off to just move on.
